Besides serving as transmission links, optical fibers have been used also to realize several types of photonic devices, namely optical amplifiers, lasers, and broadband sources. Ultrafast fiber lasers have the potential to make applications of ultrashort pulses widespread in different areas of science and technology. In particular, both stationary and pulsating dissipative ultrashort pulses as well as high energy dissipative soliton resonance pulses have attracted recently the attention of many researchers working with passively mode-locked fiber lasers. Supercontinuum fiber sources were found also to be very useful in several areas, such as optical communications, spectroscopy, optical coherence tomography, optical frequency metrology, etc. Concerning optical amplifiers, different kinds of specialty optical fibers have been developed as alternatives to conventional erbium-doped fibers (EDFs). In particular, extensive research has been done on EDFs using various glass host and co-dopant materials such as silica, fluorozirconate, chalcogenides, bismuth, aluminum, phosphorous, lanthanum, etc. Some of these materials have wider emission bandwidth that is suitable for wavelength-division multiplexing (WDM) systems. This Special Issue gathers several international experts to discuss the latest research advances and trends concerning the design, fabrication, and application of different types of optical fiber sources and amplifiers. Six papers have been submitted, which provide a nice perspective of this area. Two of them were already published in volume 39, issue 4 of this journal. One of these papers, by Yuri Barmenkov et al. (https://doi.org/10.1080/01468030.2020. 1826608), reports on the basic spectroscopic properties of a home-made holmium-aluminum-germanium co-doped silica fiber, designed for laser applications. The other paper, by Khurram Qureshi (https://doi.org/10.1080/ 01468030.2020.1829753), proposes and demonstrates a simple design of semiconductor fiber ring laser covering a broad tunable range, comprising L and extended L bands.

ABSTRACT In this paper, we present guidelines for the simulation of microstructured optical fibers (MOFs), for finding their guided modes and their nonlinear and dispersive characteristics. For the case of hollow-core MOFs, we also present guidelines for studying their photonic bands. Then, we review the results of nonlinear pulse propagation on those MOFs, showing how some of them are particularly well suited to be used as efficient supercontinuum or UV light sources.

ABSTRACT Dual optical and acoustic unidirectional transmission in two-dimensional phoxonic crystal rectangular defect connected by two mutually perpendicular waveguides is theoretically achieved. The unidirectional filtering for both optical and acoustic waves is designed by altering the phoxonic crystal waveguides and cavity to obtain the modes’ match and mismatch via the finite element method. This kind of devices has the abilities of mode convertor, wavelength filtering and unidirectional propagation for both the optical and acoustic wave, and maybe potentially applied in simultaneously manipulating light and sound.

ABSTRACT We investigate different ways of controlling the soliton explosions in passively mode-locked fiber lasers through management of the system parameters. Assuming a set of reference values for these parameters, we find that the number of soliton explosions increases with the magnitude of fiber anomalous dispersion. The soliton explosions are suppressed and the stationary pulse width is reduced for relatively low absolute values of dispersion. Similar effects can be achieved using relatively high values of the nonlinear gain. The suppression of soliton explosions is also observed for low absolute values of the nonlinear gain saturation and in situations of relatively high linear losses.

ABSTRACT In this work, single- and double-pass configurations of ytterbium-doped optical fiber amplifiers (YDFAs) have been investigated. This low quantum defect rare-earth dopant and their performance near 1 µm region has been comprehensively investigated on the basis of gain and noise figure in relation with input signal power and input pump power. The obtained results showed that at an input pump power of 100 mW, the gain was proportionally increased with ytterbium-doped fiber (YDF) length for both proposed configurations, but double-pass regime scored higher gain. This is due to the double-propagation of the forwarded and amplified spontaneous emission (ASE) signal into the active medium and hence will maximize the attainable gain near the 1 µm wavelength region. At YDF length of 5 m, the double-pass technique showed better amplification performance at a lower input signal power of −20 dB compared to the higher input signal power of 0 dB. The maximum gain and optical signal-to-noise ratio (OSNR) attained by double-pass configuration were 24.6 dB and 53.4 dB, respectively. Double-pass amplification at input signal power of −20 dB has increased the gain by 11.2 dB in comparison with the single-pass technique.

ABSTRACT In this paper, we propose a photonic crystal fiber (PCF) refractive index (RI) sensor based on the surface plasmon resonance (SPR) effect. The coupling and sensing characteristics of the proposed PCF-SPR RI sensor are investigated by the finite element method. The proposed PCF-SPR RI sensor can achieve the dual-wavebands measurement. By controlling the analytes height and incident light wavelength, the PCF-SPR RI sensor shows different sensing performances. The maximum wavelength sensitivities of the proposed PCF-SPR RI sensors can be up to 2000 and 4000 nm/RIU in the wavelength ranges of 0.75 to 1.0 and 1.2 to 2 μm, respectively.

ABSTRACT Microwave frequency down-conversion at 4.5 GHz using proposed photonic mixer is analyzed on various aspects in this manuscript. The proposed microwave photonic down-converter employs a Dual-Parallel Dual-Drive Mach–Zehnder Modulator (DP–DDMZM) that makes the system more compact than previously reported photonic mixers. Suppressed carrier modulation technique is used to increase the sideband power, which improves conversion efficiency by 20 dB as compared to dual-series modulator based mixer. To examine the performance of the proposed system for 5 G digital data transmission and reception, dispersion analysis over the length of fiber is performed. Furthermore, its performance for various digital modulation schemes is discussed.

ABSTRACT We report the basic spectroscopic properties of a home-made holmium-aluminum-germanium co-doped silica fiber, designed for laser applications. We present the ground-state and excited-state absorption spectra of the fiber along with the up-conversion emission spectrum under laser action, which served for making an energy levels’ diagram of Ho3+ ion. We discuss the ways to assess the kinetics of Ho3+ 2-µm fluorescence, focusing on measuring fluorescence lifetime from 5I7 level and non-radiative decay time from 5I6 level. The simple analytical formulae, applicable for fitting of the fluorescence decay curve, are derived, which can be useful for precise modeling of holmium-doped fiber lasers.

ABSTRACT We propose and demonstrate a simple design of semiconductor fiber ring laser covering a broad tunable range, comprising L and extended L bands. The proposed laser can be continuously tuned over 54 nm from 1578 to 1632 nm with a total output power of around 5.2 dBm and having a side mode suppression ratio (SMSR) of around 55 dB by incorporating a Fabry Pérot tunable filter. The generated output is highly stable with power and wavelength fluctuations within 0.2 dB and 0.05 nm, respectively.

ABSTRACT High-dimensional quantum key distribution (HD-QKD) can higher the secret-key capacity and tolerate more errors. Several HD-QKD experiments have been demonstrated over deployed fibers to show promising future toward high-dimensional quantum communication networks. However, the practical security of HD-QKD systems should be widely considered before large-scale application of HD-QKD systems. In this paper, we focus on the HD-QKD based on the dispersive optics (DO-QKD) with both statistical and intensity fluctuations. For the condition only with statistical fluctuations, we present the parameter estimation based on an improved Chernoff bound. When considering the condition with both statistical and intensity fluctuations, we present the parameter estimation based on Azuma’s inequality. By numerical simulations, we find that the parameter estimation for DO-QKD based on the improved Chernoff bound is tighter than the previous work in terms of the secret-key capacity and the maximum transmission distance. Moreover, we find that intensity fluctuations affect the performance of DO-QKD greatly and the effect on smaller data size is more obvious.
