Hybrid integrated optical subassembly module using a polymeric wavelength division multiplexing filter based on multimode interference for 1.31-and 1.55-mu m bidirectional operation

초록

We present a new configuration for a polymer wavelength division multiplexing (WDM) filter based on multimode interference. We developed a hybrid integrated subassembly module for 1.31- and 1.55-mu m bidirectional operation. Active devices including a laser diode with a monitoring photodiode and a receiving photodiode were integrated on a silicon optical bench (SiOB) platform using a flip-chip bonding technique. A polymer WDM filter chip made of polymethylmethacrylate was fabricated using a hot embossing technique. We then investigated the optical performance of the transmitter and receiver subassembly module using a SiOB platform. This hybrid integrated subassembly module exhibited bidirectional 2.5-Gbit/s signal modulation with a minimum sensitivity of -20.5 dBm at a bit error rate of 10(-10) and an optical crosstalk of -35 dB.
