1.55- micron polarization-insensitive optical amplifier with strain-balanced superlattice active layer
Abstract
A polarization insensitive (sensitivity less than 1 dB) semiconductor optical amplifier has been realized at 1.55 micron. The active layer consists of a strain-balanced superlattice structure. Gain polarization insensitivity on a large bandwidth (60 nm) together with a 22.5-dB signal gain and a 11-dBm polarization-insensitive saturation output power are obtained.
