Abstract: Described herein is an optical transmission cross-connect for routing wavelength signals to a bank of directionless transceivers. One embodiment (1) includes an array of four common-port fibers (3) for transmitting and receiving a multiplexed optical signal and an array of sixteen add/drop fibers (5) for receiving and transmitting demultiplexed signals including individual wavelength channels. A dispersive grism (7) simultaneously spatially separates the wavelength channels from the optical signals in a dispersion dimension. A lens (45) focuses each said spatially separated wavelength channel in the dispersion dimension. A Liquid Crystal on Silicon (LCOS) device (11) 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 (13) 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 (5).

Abstract: Described herein is a laser (1) having a cavity for supporting oscillation of an electromagnetic signal to provide lasing action. A gain element (5) provides a source of stimulated emission for amplifying the oscillating signal. The laser also includes a wavelength selective element (7), which includes a reflecting element and a polarization modifying element. The reflecting element selectively defines a predetermined wavelength and the polarization modifying element selectively modifies the polarization of the signal component at the predetermined wavelength so as to provide high selectivity. The wavelength selective element (7) rotates the signal polarization at the predetermined wavelength into an orthogonal state. A polarization filter (9) filters out the signal components having wavelengths not corresponding to the predetermined wavelength and a polarization rotation element (11) again rotates the polarization of the signal into an orthogonal state.

Abstract: Described herein is an optical channel monitor (100), including a plurality of input ports in the form of optical fibers (102) disposed in a vertical “port displacement” dimension. Each fiber (102) inputs a respective optical beam (103) having a plurality of individual wavelength channels.
