Temperature- and polarization-insensitive responsivity of a1.3-Μm optical transceiver diode with an integrated spot-sizeconverter

摘要

We have demonstrated an optical transceiver diode integrated withna spot-size converter. We clarify that the design of a detection layernis essential for the temperature- and polarization-insensitivencharacteristics of the responsivity. Because the detection layer wasnintroduced, 0.65 dB of responsivity deviation was obtained in the widentemperature range of -10°C-85°C with a high laser performance. Anspot-size converter enables the coupling loss to be 1.8 dB for anflat-end optical fiber. The frequency response was also obtained up to 1nGHz in both laser and detector modes
