Abstract

This paper proposes a high-level fluctuation tolerant optical receiver for optical packet switches and WDM cross-connects. We describe the tolerance of an experimental receiver to packet-level fluctuation and coherent crosstalk. The sensitivity of the experimental receiver was -26.9 dBm for the packet receiver configuration and -32.7 dBm for the WDM cross-connect configuration at the bit rate of 10 Gb/s. In the setup for level-fluctuating packet reception, the power-penalties of 1.1 and 4.6 dB were observed with 6 and 10 dB of fluctuation, respectively. As a WDM cross-connect, the sensitivity penalties of the receiver under the coherent crosstalk powers of -15 and -12 dB were 2.5 and 6.5 dB, respectively
