“…In coherent transmission, phase synchronization between transmitted data and a local oscillator (LO) is indispensable especially for high multiplicity modulation in quadrature amplitude modulation (QAM) transmission. For data, some phase synchronization schemes have already been developed with software [2,3] or hardware circuits [4,5]. Among them, an injectionlocking scheme is a very interesting way to realize low phase noise carrier synchronization with a simple receiver configuration [6].…”

Abstract:We report an injection-locked 60 Gbit/s 64 QAM coherent transmission employing a laser diode (LD) based heterodyne demodulation circuit. The LDs for the transmitter and receiver were InP-based external cavity laser diodes (ECLDs) emitting at 1538.8 nm. By using an injection locking technique with locking range of 100 MHz, we achieved low phase noise carrier synchronization between the data and the local oscillator with a phase noise of 0.3 deg. As a result, a polarization-multiplexed 64 QAM data signal was successfully transmitted over 160 km with a spectral efficiency of 9 bit/s/Hz.

“…Therefore, it is very useful for a real-time high multiplicity coherent transmission. By using a residual carrier as a pilot tone, a 20 Gbit/s QPSK signal has been demodulated with an OPLL [7]. To apply an OPLL to higher-order QAM, we have developed a highly precision OPLL circuit for coherent transmission with a frequency-stabilized erbium fiber laser (EFL) with a linewidth of 4 kHz as a transmitter and a frequency tunable EFL with an FM response bandwidth of over 1 GHz as an LO.…”

Abstract:We report a polarization-multiplexed 10 Gsymbol/s, 64 QAM (120 Gbit/s) coherent transmission over 150 km by using an optical phase-locked loop (OPLL) circuit employing narrow linewidth LDs. The OPLL realized low phase noise demodulation of 64 QAM signal. As a result, 120 Gbit/s data signal were transmitted with a bit error rate (BER) performance below a forward error correction (FEC) threshold of 2 × 10 −3 .
