摘要： A single hybrid electrical/optical connector simultaneously forms both electrical and optical input/output connections by a single step engagement between elements on a connector and corresponding elements of the opposite gender on a mating connector. The connector can be surface-mounted on a circuit board, and a mating connector can be vertically pluggable onto the connector. The optical elements on the connector and/or the mating connector can be detachable, which can simplify assembly of a system that includes the circuit board. The hybrid electrical/optical connector has applications for optical transceivers. The hybrid electrical/optical connector includes a housing that extends laterally along a housing plane. The housing includes electrical and optical sockets thereon. In some examples, the electrical sockets and the optical sockets are laterally arranged on opposite sides of a division plane perpendicular to the housing plane.

摘要： A vertical total internal reflection (TIR) mirror and fabrication thereof is made by creating a re-entrant profile using crystallographic silicon etching. Starting with an SOI wafer, a deep silicon etch is used to expose the buried oxide layer, which is then wet-etched (in HF), opening the bottom surface of the Si device layer. This bottom silicon surface is then exposed so that in a crystallographic etch, the resulting shape is a re-entrant trapezoid with facets. These facets can be used in conjunction with planar silicon waveguides to reflect the light upwards based on the TIR principle. Alternately, light can be coupled into the silicon waveguides from above the wafer for such purposes as wafer level testing.
摘要翻译：垂直全内反射（TIR）反射镜及其制造是通过使用晶体硅蚀刻产生凹入轮廓来实现的。从SOI晶片开始，使用深硅蚀刻来暴露掩埋氧化物层，然后对其进行湿蚀刻（在HF中），从而打开Si器件层的底表面。然后暴露该底部硅表面，以便在晶体蚀刻中，所得到的形状是具有小平面的凹入梯形。根据TIR原理，这些刻面可以与平面硅波导结合使用，以向上反射光线。或者，可以从晶圆上方将光耦合到硅波导中，用于晶圆级测试等目的。

摘要： An optical bistable silicon Raman laser is disclosed, which provides digital signal regeneration, reshaping and wavelength conversion. An apparatus according to aspects of the present invention includes an optical waveguide (119) disposed in semiconductor material (121). First and second reflectors (103, 105) are disposed in the optical waveguide. The first and second reflectors define a cavity in the optical waveguide. The cavity is to receive a first optical beam (109) having a first wavelength (lamda e). A power level of the first optical beam received by the cavity rising above a second power level results in emission of a second optical beam (111) of a second wavelength (lamda s) from the cavity until the power level of the first optical beam received by the cavity falls below a first power level. The first power level is less than the second power level.
