Matching network for microwave applications of semiconductor laser diodes (LDS): Consideration of the effects of electrical parasitics and LD carrier-dependent impedance

A complete semiconductor laser transmitter model consisting of a matching c ircuit, an electrical parasitic circuit, and a nonlinear intrinsic laser is introduced. The model is based on the transmission-line laser modeling met hod, which is very efficient and flexible. The effect of electrical parasit ics on the modulation response of the laser and the associated improvements owing to matching are also reported It has been found that the dependency of laser impedance on the carrier density is negligible.
