摘要： Described herein is a calibration system (25) for a wavelength selective switch (1). The switch (1) is adapted for dynamically switching optical beams (5, 7) along respective trajectories between input and output ports disposed in an array (3) using a reconfigurable Liquid crystal on silicon (LCOS) spatial light modulator device (17).

摘要： 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).

摘要： Described herein is an optical switch (1), including 4 common port optical fibers (e.g. 3), disposed in a vertical y dimension, a wavelength independent beam splitter (5), a switching unit (7) and 16 add/drop optical fibers (e.g. 9), disposed in a horizontal x dimension. In one direction of operation, the common port fibers (3) project respective optical beams (e.g. 11) to beam splitter (5), which physically splits each optical beam (11) into a plurality of separate sub beams (e.g. 15). The sub beams (15) are focused by a lens (17) onto respective micro-electromechanical (MEMS) mirrors (e.g. 19) of switching unit (7). Mirrors (19) direct each said sub beam (15) along respective predetermined trajectories to thereby selectively couple the sub beams (15) to corresponding add/drop optical fibers (9). Corresponding operation occurs in the reverse direction, with add/drop fibers (9) acting as input ports and common port fibers (3) providing outputs.
