Optical nonlinear material can be used as a successful optical switch. The primary requirement for proper functioning of such optical nonlinear material based logic devices is a fixed intensity level of the optical signal against a specific logic state. A transform-limited pulse may be compressed by use of a combination of a quadratic phase modulator (QPM) and a chirp filter. this communication propose a method of generating a optical pulse with fixed intensity and temporal width very short, by uses of electro-optic modulator and nonlinear material and chirp technique M3 ER -
