Abstract
Described herein is an optical transmission cross-connect for routing wavelength signals to a bank of directionless transceivers. One embodiment () includes an array of four common-port fibers () for transmitting and receiving a multiplexed optical signal and an array of sixteen add/drop fibers () for receiving and transmitting demultiplexed signals including individual wavelength channels. A dispersive grism () simultaneously spatially separates the wavelength channels from the optical signals in a dispersion dimension. A lens () focuses each said spatially separated wavelength channel in the dispersion dimension. A Liquid Crystal on Silicon (LCOS) device () separately manipulates each of the focused spatially separated wavelength channels to selectively steer the wavelength channels in a switching dimension. A micro-electromechanical mirror (MEMS) array () independently selectively directs the wavelength channels in the switching dimension such that the wavelength channels are coupled to predetermined ones of the add/drop fibers ().
