Patent abstract
A semiconductor optical amplifier (SOA) has an overall gain that is substantially polarization independent, i.e., less than 1 dB difference between transverse electric (TE) and transverse magnetic (TM) gain. The SOA includes gain and polarization rotation functions integrated onto a single substrate. According to one exemplary embodiment, a passive polarization rotation section is disposed between two active gain sections.
