Abstract

A novel optical switch structure is proposed to implement the function of cross-connection, optical power control and crosstalk reduction for optical cross-connect (OXC) in wavelength division multiplexing (WDM) optical transport networks. Based on the conventional AS/AC network structure, the proposed one deploys a set of 1x2 digital optical switches (DOS) between the AS and AC modules. Thus the optical signal power can be controlled and the crosstalk can be reduced by adjusting the driving voltage of the 1x2 DOSs. Experiments with a 4x4 polymeric thermo-optical DOS demonstrate that the power control range is more than 35 dB, and the delay for 3 dB power control is within 7.5 ms in the worst case. Analytical result also shows that the crosstalk can be suppressed at least 35 dB.
