Abstract:

Optical switching can be performed by using optical amplifiers combined with a passive waveguiding network. Recently. most of the effort in optical amplifier switch modules have been focused on monolithic switches in which the entire device is fabricated on an InP substrate together with the semiconductor optical amplifiers SOAs. In this paper, we investigate the use of SOAs with passive polymer waveguides to make hybrid switches of varying sizes. The optical amplifiers serve a dual purpose. The SOAs are used in order to gate the signal and amplify the signal in order to offset the losses associated with the passive waveguide elements as well as the losses from component misalignments in the switch module. Our analysis finds the largest switch module size that can be made with the architecture used. We also calculate the maximum number of switch modules which can be cascaded in order to retain a bit error rate BER under 10exp -9.
