✦ Synopsis

Abstract

The effect of temperature on the hysterisis behavior, threshold current, and threshold voltage of a bistable laser diode are studied by simulating its equivalent electrical circuit, developed from the rate equations. Simulations are carried out using the circuit analysis program PSPICE. The study shows that the forward threshold current, hystersis width, and threshold voltage vary exponentially with temperature. Further, the transient temperature variation in the active region due to pulsed input is also analyzed. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 233–237, 2001.
