Abstract
Optical module plays an important role in the construction of high speed communication network. Laser diode is a component of optical module, and its characteristics are dependent of temperature, so many researches are reported. In this paper, we proposed the electrical equivalent circuit of PBH-LD based on the rate equations. And, the two leakage paths exit outside the active region. One path is converted pn-diode and the other path is converted two transistors using npn-Tr and pnp-Tr. In order to reduce the leakage currents, we observed the dependence of carrier concentrations of current blocking layers using PSPICE simulator.
