Abstract: A connector to an optical fiber comprises a prism, a ferrule and an aspheric lens. The prism includes a triangular wedge element having a first surface, a second surface and a base. The ferrule guides the optical fiber so as to contact the optical fiber with the first surface of the prism. The aspheric lens is integrated on the second surface, the integrated aspheric lens being positioned so that the prism serves to redirect a light beam at an angle relative to an axis of the optical source input through total internal reflection by utilizing the base of the triangle wedge element. The aspheric lens serves to collimate the redirected light beam or focus the light beam before being redirected. This arrangement may, for example, be used within a WDM system to multiplex and de-multiplex several wavelengths of light, using a “zig-zag” optical path configuration and thin film filters to separate the wavelengths.

Abstract: An integrated zig-zag transceiver module for multiplexing and demultiplexing several wavelengths achieves a high level of integration by combining several electronic and optical elements into TO headers with lids. A photodetector, a transimpedance amplifier (TIA), a lens, and a thin-film filter are integrated into a single TO can, with the filter and lens being designed for off-axis illumination and focusing. A VCSEL, a lens, and a thin-film filter are integrated into a single TO can, with the filter and lens being designed for off-axis beam steering and collimation.

Abstract: An electromagnetic shield is formed from an etched metal sheet so that walls can be bent along etched lines to form an at least partially enclosed structure. A first wall has a first tab, such as a “male” portion, and a second wall has a second tab, such as a “female” portion. The first and second tabs interlock to hold the structure together.
