in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa)  all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...

H. S. Kwok Hong Kong University of Science and Technology Center for Display Research and Department of Electronic and Electrical Engineering Clear Water Bay, Kowloon Hong Kong Abstract. We present an optical finite impulse response (FIR) filter design method. Based on crystal birefringence, an optical FIR filter can be designed to produce arbitrary spectrum output. A mathematic model of the op...

This study proposes an innovative design method for functional optical film microstructures used in displays and applies this design to LCD backlighting to replace multi-layer optical film functional integration with composite optical film. We design a novel optical film microstructure based on light uniformity and wide-angle lumination distribution and determine the optimal optical microstruct...

Development and design of optical communication and optoelectronic systems is now necessary for the engineers in electronics and microelectronics [1]. While such design is mainly based on the physical understanding of the optics and optoelectronic phenomena, it cannot be efficiently achieved without using the design and optimization tools. Computer Aided Design (CAD) tools are now widely used i...

For the first time, the 4- and 5-port optical routers are designed by using the West First routing algorithm for use in optical network on chip. The use of the WF algorithm has made the designed routers to provide non-blocking routing in photonic network on chip. These routers not only are based on high speed Mach-Zehnder switches(Which have a higher bandwidth and more thermal tolerance than mi...

In a power grid used to distribute electricity, optical fibers can be inserted inside overhead ground wires to form an optical network infrastructure for data communications. Dense wavelength division multiplexing (DWDM)-based optical networks present a promising approach to achieve a scalable backbone network for power grids. This paper proposes a complete optimization procedure for optical ne...
