Abstract

Considerable progress has been made recently in improving the output power of semiconductor laser amplifiers by the use of multiple quantum well (MQW) active layers at 1.55 μm.1,2 More recently MQW amplifiers at 1.3 μm have been published3 which also exhibit higher saturated output power than bulk devices. In this paper we discuss the dependence on the gain and saturation output powers of 1.3 μm MQW amplifiers on wavelength.
