APPARATUS AND SIMULATION METHOD OF FABRY-PEROT LASER DIODE

摘要

PURPOSE: A Fabry-Perot laser diode(FP-LD) simulation method and a device are provided to reduce calculation time by using a gain calculation formula used in a semiconductor optical amplifier. CONSTITUTION: A FP-LD simulation device applies the average of a calculated gain and a loss and phase change during a round-trip to the whole samples of injected light(S150). The FP-LD simulation device forms composite light by adding the whole samples of the injected light to the whole samples in which a phase change is applied. The FP-LD simulation device performs round-trip a number of times which the number of the whole samples of the injected light is divided into samples included in round-trip. The FP-LD simulation device outputs the loss and the phase change in the last round-trip by applying the same to the whole samples of the light performing the last round-trip.
