Abstract
We present a compact hybrid-integrated 4 × 25.78 Gb/s TOSA based on butt coupling between DFB-LDs and silica-PLC AWG multiplexer. To obtain a low cost TOSA, high-cost conventional hermetic ceramic metal box is replaced with nonhermetic metal box. Experimentally, we demonstrate that the TOSA could achieve error-free operation for a 10 km transmission at 25°C. The packaged CWDM TOSA, which is 15.8 mm × 7.0 mm × 6.0 mm in size, shows a side-mode suppression ratio of >40 dB, a 3-dB bandwidth of >18 GHz, and error-free transmission with an average optical output power of >0 dBm and dynamic extinction ratio of >4.0 dB at 25.78125 Gb/s over a 10-km single-mode fiber for all four lanes.
