    摘要： A system for switching optical signals from a plurality of input waveguides (102) to a plurality of output waveguides (104), while balancing power in the output waveguides, and a method for its use. The system is based on an optical switch matrix (100) that includes, for each input waveguide and for each output waveguide, one or more attenuators (110, 120) that divert an adjustable portion of the optical energy entering that input waveguide to that output waveguide. Preferably, each input waveguide is coupled to each output waveguide via a pair of 2x2 Mach-Zehnder interferometers, a first of which has an idle input port (112) and a second of which has an idle output port (128). The system also includes a feedback mechanism that taps fixed portions of the power in either the input waveguides or the output waveguides, and adjusts the attenuators accordingly.

    摘要： A fiber optic directional coupler comprises first and second strands 11 of single mode fiber optic material having a portion of the cladding 37 removed from one side thereof, and means 16 positioning the strands together with the portion of the strands where the cladding is removed in close facing proximity to each other to form a region 33 of interaction in which light is transferred between the strands. Said strands diverge away from each other at the ends of the region of interaction, and the spacing between the core portions of the strands and the length of the region of interaction is such that the light makes a single transfer between the strands in the region of interaction.

    摘要： An optical interconnector (915) includes: a first vertical coupled cavity (100), a first optical waveguide (102), and a second optical waveguide (103). The first vertical coupled cavity (100) includes N identical micro-resonant cavities that are equidistantly stacked, where a center of each micro-resonant cavity is located on a first straight line that is perpendicular to a plane on which the micro-resonant cavity is located, the first optical waveguide (102) and a first micro-resonant cavity (11) are in a same plane, the second optical waveguide (103) and a second micro-resonant cavity (13) are in a same plane, the first optical waveguide (102) is an input optical waveguide, the second optical waveguide (103) is a first output optical waveguide, and an optical signal having a first resonant wavelength in the first optical waveguide (102) enters the second optical waveguide (103) through the first vertical coupled cavity (100). By means of the optical interconnector (915), the optical signal having the first resonant wavelength in the first optical waveguide (102) can be coupled to the second optical waveguide (103) after passing through the first vertical coupled cavity (100). In this way, the optical interconnector (915) can be used to implement optical signal sharing between different layers.
