4-channel/spl times/10-Gbit/s parallel laser-diode module for high-capacity optical interconnects
2002
A 4-channel/spl times/10-Gbit/s parallel LD module for next-generation high-capacity optical interconnects was developed. To suppress the inter-channel crosstalk, a PPLC platform with a channel-pitch conversion function was also developed. Four un-cooled 1.3-/spl mu/m InGaAlAs FP-LDs were mounted on separated electrodes of the PPLC platform by passive alignment; thus, the module is compact and low cost. Crosstalk is as low as -40 dB. The module has a total throughput of 40 Gbit/s over 300-m transmission without suffering any degradation caused by inter-channel crosstalk. Our proposed 4-channel/spl times/10 Gbit/s parallel LD module can be applied to next-generation high-capacity optical interconnects.
