摘要： A semiconductor-based optical switch engine switches input light from an input switch element to an output switch element and directly couples through an optical waveguide each output of the input switch element to a respective input of the output switch element. The switch architecture reduces signal cross-talk because each signal passes through the optical switch engine using a dedicated optical path. The optical switch engine also maintains a consistent signal-to-noise ratio among all the paths through the switch and reduces the total number of switch points through which an optical signal may pass.

摘要： An optical switching system includes a substrate, a microelectromechanical system (MEMS) input mirror, a MEMS output mirror, and an opposing mirror. The substrate is configured to carry an input light source and an output light source spaced from the input light source. The microelectromechanical system (MEMS) input mirror is carried by the substrate. The MEMS output mirror is carried by the substrate and is spaced from the MEMS input mirror. The opposing mirror is disposed opposite the substrate and is configured to communicate optically with an input light source and an output light source carried by the substrate. The input mirror optically couples an input beam from the input light source via the opposing mirror to a location on the opposing mirror with the output mirror via the opposing mirror. The output mirror optically couples the location on the opposing mirror with the output light source via the opposing mirror. In one case, the input light source and the output light source each comprise an optical fiber. An optical switch and an electromechanical device are also provided.

摘要： An optical switching assembly comprised of a substrate, a first plurality of waveguides in a first plane in the substrate, a second plurality of waveguides in a second plane parallel to said first plane in the substrate, the optical signals being selectively transferable from one substrate to the other. The second waveguides cross the first waveguides at an angle and the first waveguides each have a segment extending generally parallel to a segment of the second waveguides at the crossing. Controllable coupling material is disposed between the segments of the waveguides at the crossing and a control circuit is employed for selectively changing the index of refraction of the coupling material by electrical or thermal means.

摘要： A fiber ribbon includes a plurality of first segments of optical fibers that extend in a planar side-by-side arrangement having a first predetermined pitch. A fiber-fan-out including a plurality of second segments of the optical fibers extends in a diverging arrangement from the fiber ribbon. A fiber holder extends across the plurality of second segments of the optical fibers for maintaining a plurality of terminal portions of the second segments in a second predetermined pitch that is greater than the first predetermined pitch so that the terminal portions can each be optically coupled to a corresponding optical subassembly (OSA) of a plurality of OSAs arranged in a linear array. An alternate embodiment uses a second fiber holder in place of the fiber ribbon. The holders can be replaced with a common housing assembly spanning all but the terminal portions of the optical fibers.

摘要： A three-dimensional optical switch using three-dimensional rewritable waveguides in a photosensitive substrate. At least two light beams are used to illuminate the substrate in the region where the waveguide is to be written. The refractive index of the substrate changes at the points where the beams intersect. Therefore, the light beams can be directed to create a three-dimensional waveguide in the photosensitive substrate. A plurality of inlet ports in one surface of the substrate are thereby connected to a plurality of outlet ports on another surface of the substrate. Alternatively, the inlet ports and the outlet ports may be on the same surface of the substrate. The invention also provides methods of creating waveguides in photosensitive media using the device described herein.

摘要： An array of n-wavelength vertical cavity surface emitting lasers (VCSELs) can be grown with precise and repeatable wavelength control. First, a foundation VCSEL structure is grown on a substrate. Next, n-paired layers of AlGaAs and InGaP are grown, where n is the desired number of different wavelengths. Next, one of the n regions is masked and etched. The steps of masking and etching are repeated until all n regions are etched. Finally, the upper VCSEL structure is grown.

摘要： The WDM receiver includes a wavelength demultiplexer, a detector array and a signal extractor. The wavelength demultiplexer receives an n-channel optical input signal and transmits the n-channel optical input signal to m optical outputs. Each of the optical outputs receives a wavelength band centered at a different wavelength. The wavelength bands have a center-to-center wavelength spacing of Δλ′. The detector array is composed of m detector elements coupled to the wavelength demultiplexer. Each of the detector elements generates a detection signal in response to light received from one of the optical outputs of the wavelength demultiplexer. The signal extractor receives the detection signals from the detector array and converts the detection signals to an n-channel receiver output signal, each channel of which corresponds to a different one of the n channels of the optical input signal. The WDM receiver is able to detect optical signals that are closely spaced in wavelength, even when the optical signals have off-center of varying wavelengths.

摘要： A first plurality of stages each support a ferrule surrounding an end portion of a corresponding one of N optical input fibers. A second plurality of stages each support a ferrule surrounding an end portion of a corresponding one of M optical output fibers. Mechanical mechanisms translate the stages along a plurality of orthogonal X and Y axes to align a facet of a selected one of the N input optical fibers with a facet of a selected one of the M output optical fibers. The stages of the input optical fibers, the output optical fibers, or both, have mechanical mechanisms for moving the ferrules along Z axes perpendicular to the X and Y axes into and out of alignment holes of a central panel to physically mate the facets of the coupled fibers.
