Low-cost plastic package transceiver components for large core fiber systems

Abstract

We have developed low cost optical components based on electronics-style plastic packages for large core fiber systems such as polymer cladded silica (PCS) fiber systems. The VCSEL based transmitter demonstrates data rate up to 500Mbps and output power variation < 0.2dB over a wide ambient temperature range from -40/spl deg/C to 105/spl deg/C. Preliminary reliability data of the VCSEL transmitter shows no output power degradation after 500 cycles of temperature cycling from -40/spl deg/C to 125/spl deg/C. We have also fabricated MSM-PD for high speed large core fiber applications. The coupling tolerances are relaxed for 80/spl mu/m in lateral axis and 4000/spl mu/m in longitudinal axis, respectively. The MSM-PD based receiver exhibits a high sensitivity of -18dBm at a data rate of 3.2Gbps.
