Abstract

It has been shown that in addition of amplification function, semiconductor laser amplifiers (SLAs) can also be used as modulators and detectors with large bandwidth [1]-[2]. Therefore, optical bidirectional buses can be composed of SLAs working alternately as a modulator or a photodetector [3]. Such a bus has recently been reported [4] and it would afford the following advantages: good contrast between bit levels "0" et "1", high bit rate, signal power correctly maintained, bidirectional transmission assumed by one optical fiber.
