1.3 μm DFB-VUG laser module with a hybrid amplifier-driver circuit for half-duplex transmission

摘要

We describe an efficient 1.3 μm half-duplex transceiver comprising a very low capacitance high speed 1.3 μm DFB-VUG laser chip, a 70 % coupling efficiency single mode lensed fibre and a preamplifier-IC-driver circuit assembled on an alumina sub-mount. A 4 GHz transmitter modulation bandwidth and a 1.9 GHz receiver bandwidth are demonstrated together with a receiver sensitivity of -26.5 dBm at 622 Mb/s.
