Abstract :
An array of 1.3 μm FP-LDs with their anodes and cathodes separated channel by channel was developed to suppress interchannel electric crosstalk at high frequency. Low crosstalk of less than -30 dB was obtained between neighbouring LDs at 3.125 GHz. This is sufficiently low that BER characteristics observed under asynchronous operation of a four-channel LD array were found to be no worse than those under single channel operation
