Abstract: An optical add/drop module includes an add channel (66), an input channel (68), a drop channel (70) and an output channel (72), with each channel aligned to transmit or receive light reflected from a common mirror (74) in at least one state of the add/drop module. Rotating the mirror changes the state of the module. In the module's add/drop state, light from the input channel (68) reflects from the mirror into the drop channel (70) and light from the add channel (66) reflects off the mirror (74) to the output channel (72). In the module's pass through state, light from the input channel (68) reflects off the mirror into the output channel (72) and light from the add channel (66) reflects off the mirror (74) to a position other than the drop channel (70). Arrays of add, input, drop and output, channels can be coupled to a linear array of independent micro-electromechanical (114) mirrors to provide an integrated set of optical add/drop modules.

Abstract: A tap coupler device for an optical array is formed either in a waveguide structure or in a V block in which a fiber array may be mounted. The tap coupler device may include a substrate with main (18) and tap (22) waveguides formed therein, and waveguide tap couplers formed in the substrate for diverting a portion of the optical signal from the main waveguides (18) to corresponding tap waveguides (22). Tapping may be performed by a y coupler or by an evanescent directional coupler. Another variation includes a substrate including waveguides, with the surface of the substrate where the waveguides end inclined to reflect a portion of the signals in the waveguides toward the top surface of the substrate. Yet another variation includes an input V block having input fibers. The surface of the V block where the input fibers terminate is inclined to reflect a portion of light signals from the input fibers toward the top surface of the V block.

Abstract: An assembly that could be used either as a switch or an attenuator includes two or more optical channels defined by lithography within a substrate. The two or more optical channels are positioned so that the ends of the optical channels are at or near an edge of the substrate. A moveable MEMS mirror is positioned near the edge of the substrate and the openings, with the face of the mirror positioned to receive an optical signal from one of the optical channels. The mirror can direct an optical signal from one of the optical channels into another of the optical channels. Mirror position can be changed to alter the path of the optical signal and to change the coupling between the optical channels. In this way, the assembly of optical channels within the substrate and the MEMS mirror can act as a switch or as an attenuator.
