FM-to-AM conversion for angular filtering based on transmitted volume Bragg gratings (TBGs) is discussed. Simulation results show that a narrower spectral selectivity of TBGs led to stronger FM-to-AM conversion. Good angular selectivity and a wide bandwid
A self-seeded fiber laser incorporated with a fiber Bragg grating external cavity semiconductor laser (FBGECL) and a Mach-Zehnder interferometer (MZI) were reported in this paper. The MZI provided a Q-switching with response time in the order of micro-sec
A robust design for a photonic crystal fiber (PCF) based on pure silica with small normal dispersion and high nonlinear coefficient for its dual concentric core structure is presented. This design is suitable for flat broadband supercontinuum (SC) generat
A novel label abstraction and erasion scheme based on a Fabry-Perot semiconductor optical amplifier (FP-SOA) is proposed for all-optical separation of the bit-serial label from payload and its performance is investigated by simulation. Important features
A new kind of tunable optical filter is proposed for DWDM optical communication application. It is based on cascaded polarization interference filter (PIF). The period and bandpass width of each PIF are decided by its optical path difference between o-ray
Microstructure and misfit dislocation behavior in InxGa1-xAs/InP heteroepitaxial materials grown by low pressure metal organic chemical vapor deposition (LP-MOCVD) were analyzed by high resolution transmission electron microscopy (HRTEM), scanning electro
