ABSTRACT
We demonstrate a single polarization monolithically integrated coherent receiver on an InP substrate with a SOA preamplifier, a 90° optical hybrid, and four 40 GHz UTC photodiodes. Record performances with responsivity above 4 A/W with low imbalance <1 dB and error free detection of 32 Gbaud QPSK signals were simultaneously demonstrated.
ABSTRACT
We present for the first time a high performance APD-based linear burst-mode receiver (BM-RX) with a record wide dynamic range of 31 dB. The APD multiplication factor is controlled from burst to burst within 60 ns by an on-chip self-generated M-control signal. In the experiment, a total optical budget of 54 dB is achieved with a single SOA-based reach extender for 10 Gb/s upstream. With electronic dispersion compensation, the APD linear BM-RX with a wide dynamic range relaxes the requirement on optical components and lowers the system cost, especially at the optical network unit (ONU) side.
ABSTRACT
This paper presents a high performance DC-coupled 10 Gbit/s APD-based optical burst-mode receiver (BM-RX) for symmetric 10G-GPONs. The BM-RX can handle upstream bursts with a loud/soft range wider than 24.0 dB, and the measured sensitivity is -30.0 dBm at BER = 10(-3) after a start of burst settling time no longer than 51 ns. This paper also investigates, for the first time, the inter-burst guard time required for a 10 Gbit/s BM-RX with auto-reset generation, while the PON operates upstream at a high raw BER and is using FEC.
