摘要： A process for forming electrical contacts for a semiconductor light emitting apparatus is disclosed. The light emitting apparatus has a first layer of first conductivity type, an active layer for generating light overlying the first layer, and a second layer of second conductivity type overlying the active layer. The process involves forming at least a first and a second elongate electrical contact through the second layer and the active layer to provide electrical connection to the first layer, the first and second contacts oriented at an angle to each other, the first contact having a first end in proximity with the second contact, the first end being sufficiently spaced apart from the second contact such that when current is supplied to the first layer through the contacts, current contributions from the first end of the first contact and the second contact in an area generally between the first end and the second contact cause a current density in the area that is approximately equal to a current density elsewhere along the first and second contacts.

摘要： An optical switch is presented. In a first state, a trench is filled with index matching fluid so that light from a first waveguide passes through the trench to a second waveguide. In a second state, a bubble is formed within the index matching fluid so that light from the first waveguide is reflected at the trench to a third waveguide. The bubble is formed by heat so that volume of the bubble is substantially less than total volume of the trench, resulting in pressure within the bubble not being substantially increased by pressure exerted by sidewalls of the trench.

摘要： A pressure sensitive cursor control suitable for applications that include cellular phones and personal data assistants includes a pressure sensor array suitable to detect a human fingerprint. Cursor control is provided by subtle finger movement. Sequential images of the finger are captured and compared to determine planar movement or data entry. Performance may be improved by sampling zones within the captured image and comparing the zones with those in an earlier image. Performance could also be improved by subsampling the array. While the full resolution of the pressure-sensing array is needed to capture ones fingerprint and execute an authentication function only a subsampled image from the array is needed to derive meaningful navigation data. The pressure sensor array is designed on a glass substrate in order to drive down the unit cost. The silicon companion chip where the data is interpreted also drives the array and can therefore sub-sample the array when navigating and/or get a full resolution image when authenticating.

摘要： A light transmission system includes a laser, an optical fiber and a transfer lens. The fiber optic transfer for transfers light emitted by the laser into the optical fiber. The transfer lens includes a hyperbolic collimating surface for receiving and collimating light originating from the laser. The transfer lens also includes an output lens surface shaped so that light reflected from the end of the optical filter is not focused at a location at which the light is emitted by the laser. Additionally, in various preferred embodiments light launched into the optical fiber avoids index anomalies on the axis of the optical fiber and at the core-cladding interface.
