Abstract
This paper presents a feedback Arrayed-Waveguide Grating-Based (AWG) optical packet switch proposed in an EPSRC-funded project, WASPNET (WAvelength Switched Packet NET work). The feedback configuration allows packet priority routing at the expense of requiring a larger AWG thus increasing the crosstalk. In this paper, it is shown that some inputs of an arrayed-waveguide grating may be left unused in order to reduce or even eliminate homowavelength crosstalk.
