Conventional Q-switched mid-infrared fiber lasers normally rely on bulk optical elements for assembling mid- infrared resonators, which will possibly undermine the reliability and robustness of the fiber laser systems. Here, we address the challenge through demonstrating, for the first time, a miniaturized 3 μm Ho3+:ZBLAN fiber laser passively Q-switched by topological insulator Bi2Se3. The linear all-fiber cavity simply consists of a home-made 1153 nm fiber laser as pump source, a 2- m Ho3+:ZBLAN fiber, and two fiber end-facet mirrors. By inserting the few-layer Bi2Se3 saturable absorber into the laser cavity, stable mid-infrared Q-switched pulses at 2920.6 nm were generated at a low threshold of ~70 mW, and the pulse repetition rate can be linearly tuned from 24.97 to 56.13 kHz. The maximum average power obtained was 315 μW, corresponding to the narrowest pulse duration of 1.54 μs and the maximum pulse energy of 6 nJ, relatively.

We propose a marketplace where multiple network operators coexisting on the same passive optical network (PON) infrastructure can share their excess capacity. We designed a double auction to assure efficient allocation of optical access capacity.

An optical fiber biosensor is demonstrated exploiting the detection of microfiber light polarization modulation. Microfiber is immersed in the magnetic fluid (MF) which contains carboxylated magnetic nanoparticles (CMNPs), without needing the modification of the microfiber surface. While, only an external magnetic field is utilized. Self-assembly of CMNPs is induced after adding bovine serum albumin (BSA) into the MF. The microfiber light polarization modulation relaxation time is prolonged, when external magnetic field is applied or removed for a given period of time. The concentration of BSA solution can be detected by detecting the maximum light polarization degree, or detecting the difference between the maximum and minimum polarization degree. The signal processing system of the biosensor is not only simple but also cost effective. Moreover, biomasses, such as virus, biotin, DNA, and phosphate compounds can also be detected using our scheme.

In this paper, we reported the design, fabrication and preliminary measurements of an integrating periodically capacitive-loaded travelling wave electrode (CL-TWE) Mach- Zehnder interferometer (MZI) modulator based on InP-based multiple quantum well (MQW) optical waveguides. The device configuration includes an optical MZI, a DC electrode, two phase electrodes, a U-electrode and an I-electrode. It was fabricated by standard photolithography, ICP dry etching, electroplating and etc. Measurement results show that the EO modulator has a propagation loss of about 9.4 dB/cm and an electric bandwidth of larger than 40 GHz.

We design and fabricate a chip-scale optical phased array (OPA) with a uniform emitting structure composed of bent waveguides. This silicon-on-insulator based device demonstrates aliasing-free beam-steering over the entire field-of-view available (−34°~34°), with a far-field addressability of 6.71°. In addition, the steering process exhibits a plateau envelope, with an intensity fluctuation of less than 0.45 dB from −30°~30°.
