摘要： Unwanted dynamics in an optical switch are eliminated by calculating a set of new parameter values that shape an input command signal applied to the switch in accordance with an algorithm that randomly varies initial parameter values within certain constraints. The input command signal is applied to the mirror actuators in order to produce a response by the optical switch. A cost function value indicative of oscillations present in the response is calculated and compared to a previous cost function value. If the cost function value is less than the previous cost function value, the new parameter values are stored and designated as the initial parameter values for a next iteration. Following repeated iterative calculations to shape the input command signal, an optimal set of parameter values are produced. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： Our invention relates generally to an optical switch (31) and an optical router (10) to rapidly route signals from particular channels (22, 24) within an optical band by using optical switches (20) which utilize a controlled whispering gallery mode (WGM) resonance of dielectric microspheres (S1, S2, S3) to optically switch signals. Another invention relates to optical filters which use a WGM resonate structure (150) to isolate and switch specific optical signals between waveguides (F1, F2). In other inventions, the filter (100) is switched nullon/offnull by signal loss within a WGM resonate structure (150) which disrupts the WGM resonance; the filter (100) isolates and switches a specific wavelength signal from among a group of signals of different wavelengths; and is switched nulloffnull by adjusting the index of refraction of the resonate structure to become substantially similar to the index of refraction of the surrounding medium.

摘要： An optical micro-electro-mechanical system (MEMS) switch is disclosed. In a preferred embodiment the optical MEMS switch is used as an MnullN optical signal switching system. The optical MEMS switch comprises a plurality of optical waveguides formed on a shuttle for switching optical states wherein the state of the optical switch is changed by a system of drive and latch actuators. The optical MEMS switch utilizes a latching mechanism in association with a thermal drive actuator for aligning the waveguide shuttle. In use the optical MEMS switch may be integrated with other optical components to form planar light circuits (PLCs). When switches and PLCs are integrated together on a silicon chip, compact higher functionality devices, such as Reconfigurable Optical Add-Drop Multiplexers (ROADMs), may be fabricated.

摘要： A monolithic optical module of injection-molded high temperature polymeric resin combines an optical turn of typically 90 degrees together with dual or triple beam paths. No additional piece parts are necessary for achieving the optical turn, since this occurs by total internal reflection (TIR), and no additional piece parts are necessary for dual monitoring, which is realized by means of an air-gap functioning as a dual beam-splitter plate. The monolithic optical module further includes integrally surfaces for accurate alignment of the module with external optical elements, and can additionally include integral optical elements, for example lenses and thin film coatings.

摘要： An apparatus for optical coupling having a first array of individual waveguides optically communicating with a free space region at a first junction and each waveguide having a tapered region proximate the junction where a gap spacing between tapered regions of adjacent individual waveguides is substantially constant is proposed. The gap spacing is a minimum amount of space between adjacent individual waveguides. The first array of individual waveguides also has a horn region immediately proximate the tapered region and opposite the first junction with an increasing width whose maximum establishes the gap spacing.
