摘要： Devices utilize elements carried by a fluid in a microchannel to switch, attenuate, shutter, filter, or phase shift optical signals. In certain embodiments, a microchannel carries a gaseous or liquid slug that interacts with at least a portion of the optical power of an optical signal traveling through a waveguide. The microchannel may form part of the cladding of the waveguide, part of the core and the cladding, or part of the core only. The microchannel may also have ends or may be configured as a loop or continuous channel. The fluid devices may be self-latching or may be semi-latching. The fluid in the microchannel is moved using e.g., e.g., electrocapillarity, differential-pressure electrocapillarity, electrowetting, continuous electrowetting, electrophoresis, electroosmosis, dielectrophoresis, electro-hydrodynamic electrohydrodynamic pumping, magneto-hydrodynamic magnetohydrodynamic pumping, thermocapillarity, thermal expansion, dielectric pumping, and/or variable dielectric pumping.

摘要： Provided are a method, system, and device for passing a plurality of light beams though an array of waveguides wherein at least one waveguide is coupled to a test structure which exhibits an insertion loss dependent on a known polarization. For each of a plurality of adjacent waveguides of the array including the one waveguide, a first wavelength response associated with a first polarization, and a second wavelength response associated with a second polarization, may be measured. In one example, polarization may be identified as the known polarization if the peak value of one wavelength response of the test structure is less than the peak value of another wavelength response of the first test structure. In one embodiment, unknown polarizations in the polarization response of an optical component having multiple correlated outputs may be identified. Other embodiments are described and claimed.

摘要： Light transmissive structures include a light transmissive substrate that includes optical microstructures. The optical microstructures have a geometric feature that is configured to reduce glare in light transmitted through the light transmissive structure. Moreover, the plurality of optical microstructures also have a geometric feature that is configured to vary randomly and/or pseudorandomly across the light transmissive substrate so as to diffuse light transmitted through the light transmissive structure. Related fabrication methods are also described.
