Design and simulation of novel all-optical fundamental X-NOR and NAND logic gates based on two dimensional photonic crystals are reported in this paper. In a photonic crystal self collimated beams are partially transmitted and partially reflected with a phase lag at a line defect in Γ-X direction. The phase shifter is employed, the reflected and(More)
We propose a new optical signal processing technique using optical MEMS for high speed beam steering in base stations. Micromirrors fixed to one of the electrodes for two pairs of parallel plate electrostatic actuators are displaced to control the phase and amplitude of the incoming optical signal. This weighted signal is heterodyned with the reference(More)
Photonic crystals are promising technology in future optical signal processing and optical computing. Design and simulation of novel all-optical fundamental XOR and OR logic gates based on two dimensional photonic crystals utilizing self-collimation and splitting mechanism are reported in this paper. In a photonic crystal, self collimated beams are(More)
Design and simulation of a Micro Electro Mechanical Systems (MEMS) based optical signal processing beam former for cellular network base station is reported in this paper. The optical signal destined for a mobile terminal is split into eight equal-intensity signals. Each signal is complex weighted by controlling the phase and amplitude using a pair of(More)
In this paper, design and simulation of optical beam former for cellular coherent optical OFDM (CO-OFDM) system with high data rate is addressed. We first discuss the generation of CO-OFDM symbols and then present the MEMS (micro electro mechanical systems) based optical beam former. The optical OFDM signal destined for a mobile terminal is split into eight(More)
