Some Investigations with Ultra High Speed Low Power All Optical digital Logic Gates

Abstract

Abstract

This paper illustrates design for an all-optical optical inverter and universal digital logic NAND gate using NRZ format, realized by MZI structure. Miscellaneous evaluations have been done to examine the designs performance in terms of their generated output waveforms.  Simulations have been done for significant design parameters as chirp factor, laser power and bit error rate at different data-rates. Optical Logical gate outputs have been verified. It showed good design performance with variation in the low (<9) line width enhance, low chirp factor, low (-13dBm) normalizer average power, low (0.5) confine factor, for pump current more than 0.15 A with choice of the laser power. This schematic is straightforward, compact, shirks recurrent optoelectronics translations consequently power consumption is low. The outcomes are well supportive for the design of sophisticated all-optical logic executions and to storage devices.
