摘要： A MEMS based alignment technology based on mounting an optical component on a released micromechanical lever configuration that uses multiple flexures rather than a single spring. The optical component may be a lens. The use of multiple flexures may reduce coupling between lens rotation and lens translation, and reduce effects of lever handle warping on lens position. The device can be optimized for various geometries.

摘要： An optical assembly comprises a combination of semiconductor optical gain elements, microlenses, and a wavelength-selective planar lightwave circuit (PLC) that routes light of different wavelengths from a different inputs to a single output. The microlenses couple light from the semiconductor optical gain elements into the PLC. The positions of the microlenses can be adjusted using micromechanical holders that are part of their carriers, and are free to move initially, and fixed in place after optimization of the optical coupling. In operation, the gain elements are activated simultaneously, with one wavelength of light lasing within each gain element. All output wavelengths of light exit from a single output of the PLC in a single spatial mode.

摘要： Multiple broad area lasers are coupled to a planar lightwave circuit, where the waveguides come together to form a single wide emitting aperture. A tapered lens is used at the output of the planar lightwave circuit to transform the highly asymmetric mode into a conventional round mode. This configuration allows much higher “brightness”, allowing 10 or more 100 um wide broad area lasers to be coupled into a single 100 um core multimode fiber. This is considerably more efficient than the standard method of combining a single 100 um wide broad area laser to a 100 um core multimode fiber.

摘要： One or more single mode waveguide devices are fiber coupled such that signals to an optical element affect the coupling of the waveguide device to an optical fiber. A number of systems and methods are disclosed to adjust the coupling of the waveguide device to the optical fiber. These include dithering the tunable optical element at different frequencies along differing axes and using a lock-in technique to derive an error signal for each degree of motion, using a beamsplitter to form a secondary image of the focused beam on a position-sensitive detector, the use of a chiseled fiber to generate reflections from the angled facets, using an additional laser for a secondary image, or obtaining a secondary image from an angled fiber or a parasitic reflection.

摘要： A demultiplexing apparatus for wavelength division multiplexed optical communications makes use of an interleaver to separate alternating wavelengths into separate wavelength groups. These separate wavelength groups may then be demultiplexed using conventional demultiplexers. An optical coupler such as an optical circulator or a curved grating is used to direct the reflected wavelengths to a separate output path. The interleaver preferably has a square wave reflectivity response in the wavelength domain, and reflects every other wavelength to a separate output path than those wavelengths that are transmitted past the interleaver. The interleaver may be a diffraction grating that may be apodized or chirped. The grating may also be a sampled grating structure. Alternatively, the interleaver may be a planar waveguide that has a periodic change in the refractive index conditions of a section of the waveguide.

摘要： A variable index distributed mirror is disclosed used for high resolution reflective displays that are thin and have high resolution, reflectivity and contrast; wide viewing angle; low power consumption; and low voltage operation. The mirror is electrically switchable or variable between substantially transparent and reflective states. The mirror has alternating layers of a first material having a fixed refractive index, and a second material having a variable refractive index. The second material may be a nematic liquid crystal. The alternating layers are located between a pair of electrodes. The variable refractive index approximately equals the fixed refractive index in the transparent state and differs from the fixed refractive index in the reflective state. The variable refractive index varies in response to a signal applied across the electrodes. The mirror is tuned to a particular color to form a monochrome display. Three such mirrors, each individually driven and tuned to different colors, form a color display. For a black and white monochrome display, the three mirrors are driven collectively.
