In 40-Gb/s optical systems, it is impossible to neglect the electronic dispersion of polarization-mode dispersion (PMD). As the data rate is increased, the maximum useful length of the fiber decreases according to the square of the increase. With the development of VLSI and DSP technologies, the electronic dispersion compensation for optical network has aroused greater world attention. In this paper, the performance of decision feedback equalizer (DFE) in PMD-limited 40-GB/s optical links is analyzed by using Matlab/Simulink. A simple equalizer circuit, in fold-cascade traveling-wave filter topology, is presented and the results based on S-parameter simulations show that a DFE equalizer consisting of a 3-tap feed forward equalizer (FFE) and a 2-tap feed back equalizer (FBE) can mitigate PMD effectively.

Yb-doped silica nanoparticles were fabricated in a MCVD process. Their compositions and doping levels were well controlled. The nanoparticles are of about 21.3 ± 4.6 nm in size, and exhibit the Yb3+-absorption in NIR and several photodarkening bands in UV-Vis. The photodarkening strongly depends on the compositions.

An optical switch is fabricated based on nanocrystalline vanadium oxide (VOx) thin film using micromachining technology. An “on” state with semiconducting phase to an “off” state with metallic phase is controlled by applying a DC power to Aurum electrodes of the optical switch. The optical switching performance for the fabricated device is investigated at optical communication wavelength of 1.55µm. The heater power requires to achieve switching action is about 15mW. The testing results show that the extinction ratio and switching response time are 14dB and 2ms, respectively.

As the applications of circular polarization (CP) antennas are widely used in the wireless communications, it is significant to improve the CP antenna performance in aspect of axial ratio at the boresite direction. A good CP performance is always desired. In this paper, we fabricate the amendatory one-dimensional photonic crystals for SHF reflector antenna based on previous simulation results to compensate the circular-polarization discrimination as encountered in many antenna's applications. The goal is to widen the beamwidth of radiation for crossed-dipole. The performance is evaluated by measuring the 3dB axial ratio. Transfer matrix theory of multi-layer theory is used to solve the field distribution cross layer. Although some tabulate plane-based (TPB) compensations can achieve a great improvement for the crossed-dipole based reflector antenna, but it can only compensate the CP in a specified direction and may distort in other directions. The one-dimensional approach can smooth the discrimination introduced by the reflector and noise. The energy distribution of TE/TM polarizations are regulated with a one dimensional photonic crystal to achieve a broader beamwidth, also the reflector antenna is fabricated and measured to validate the efficiency of the proposed approach. The measured results show that the beamwidth is much wider than that before compensation. The gain of 3D plot and the radiation patterns are also shown to verify if the side effect of compensation.

A novel, dynamic, non-invasive, high-speed dynamic optical coherence elastography (OCE) system has been developed for quantitatively mapping tissue biomechanical properties utilizing spectral-domain optical coherence tomography (OCT) and a mechanical wave driver. This dynamic OCE technique is based on solving wave equations without speckle tracking algorithms. Using phase-resolved imaging, we demonstrate OCE can map dynamic elastic moduli of normal and neoplastic ex vivo human breast tissue. This dynamic OCE technique is used to determine in vivo skin biomechanical properties based on mechanical surface wave propagation. Quantitative Young's moduli are measured on human skin from different sites, orientations, and frequencies.

Fiber optical parametric amplifiers (OPAs) are based on the third-order nonlinear susceptibility of glass fibers. If two strong pumps and a weak signal are fed into a fiber, an idler is generated. Signal and idler can grow together if pump power is high enough, and phase matching occurs. Until recently, impressive performance of fiber OPAs has been demonstrated in different respects. However, second-order effects should be addressed before OPAs can be utilized in practical applications. Here we report some of these effects, either exploiting them as in the parametric processor such as optical logic gates, inverted and non-inverted wavelength converter, and ultra-wideband monocycle and doublet pulses generator, or suppressing them as in the optical amplifier for WDM systems.
