Semiconductor laser and system for and method of performing digital optical communications using such semiconductor laser

摘要

A digital optical communication method transmits an optical signal over a long distance with a reduced power penalty. The method has the step of shaping the waveform of the optical signal to be transmitted through the optical fiber to increase the frequency thereof before the waveform is stabilized when the optical signal starts increasing in level at the time the optical signal is applied to the optical fiber.
