摘要： A Fabry-Perot optical switch includes a saturable absorber surrounded by a pair of mirrors. Coupled to the saturable absorber is an input waveguide, an output waveguide, and a control beam waveguide. In the absence of light input to the control beam waveguide, the saturable absorber prevents an input signal on the input waveguide from passing through and being output on the output waveguide, thus placing the switch in an “off” state. In the presence of light input to the control beam waveguide and incident on the saturable absorber, the saturable absorber allows the input signal to pass through and be output on the output waveguide, or be reflected and output on the output waveguide, thus placing the switch in an “on” state.

摘要： A multiplexing/demultiplexing system has a multiplexor that includes a first plurality of optical switches having a plurality of outputs and a first plurality of optical delay elements coupled to the optical switches. A source of optical light is coupled to the delay elements, and an optical combiner is coupled to the plurality of outputs and a source of framing pulses. A demultiplexor includes a first and second splitter, and a threshold detector coupled to the first splitter. The demultiplexor further includes a second plurality of optical delay elements coupled to the threshold detector, and a second plurality of optical switches coupled to the second splitter and the second plurality of delay elements.

摘要： An optical filter that includes a resonator cavity comprised of a saturable absorber material is provided. An input signal waveguide, a non-resonant wavelengths output waveguide, and a resonant wavelength output waveguide are coupled to the cavity. A refractive index of the saturable absorber material is altered so that a resonant wavelength output is directed down the resonant wavelength output waveguide and non-resonant wavelengths are directed down the non-resonant wavelengths output waveguide.
