Low-Polarization, Broad-Spectrum Semiconductor Optical Amplifiers

“…Unlike polarization-sensitive SOAs, polarization-insensitive SOAs can amplify both TE- and TM-mode optical signals simultaneously, thereby enhancing the flexibility and scalability of networks. Therefore, polarization-insensitive SOAs are poised to become the core devices for future long-distance, ultra-high-speed coherent optical communication [ 18 , 19 , 20 ].…”

Ultrawide-band Low Polarization Sensitivity 3-µm SOI Arrayed Waveguide Gratings

“…1(b). PI and UWB WSS design can be realized by employing UWB PI AWGs and array of PI SOAs [5] that operate at different bands. The availability of a PI AWG that can operate on multiple bands will highly simplify the implementation of a hybrid wideband PIC-WSS by flexibly adapting the SOA array operating at the desired band.…”
