An illumination source for use in projectors and the like. The illumination source includes a light source that generates a two-dimensional emission pattern having a light intensity that varies as a function of position in the emission pattern. A collector collects the light from the light source and illuminates an exit aperture therewith. The illuminated exit aperture has a two-dimensional emission pattern with a light intensity that varies as a function of position in a manner that is more uniform as a function of position than the emission pattern of the light source. An imaging optical element images the exit aperture onto a surface. The collector is preferably a compound parabolic concentrator or a compound elliptical concentrator. In one embodiment of the invention, a partially reflecting film is placed between the exit aperture and the imaging optical element. The partially reflecting film reflects light of a first polarization state back into the collector and transmits light of the orthogonal polarization state.

A polarization device comprising: a light path; a micro lens array disposed in the light path for separating light into a plurality of individual beams of light; a polarization filter disposed in the light path to receive a plurality of the beams of light and to transmit the received light of a desired polarization state and reflect the received light of a perpendicular polarization state that is perpendicular to the desired polarization state; and a reflecting polarization converter disposed to receive and reflect the reflected light of the perpendicular polarization state and to convert the perpendicular polarization state to the desired polarization state.

This disclosure provides an image screen having anti-reflective qualities, such as might be used in projection television. In particular, an opaque black layer is formed on a front, viewer-side of the screen using the transmissive properties of the projection screen itself, e. g. , as defined by a bubble lens array on the back side of the screen. In one embodiment, light is transmitted through a Fresnel lens, through a bubble lens array, and onto a photoresist to expose transmissive âpinholesâ in the photoresist. Photoresist is then removed in unexposed areas, and an anti-reflective material is deposited over the entire viewer-side of the screen. Remaining photoresist is then removed from transmissive areas to leave the anti-reflective material in all areas not receptive to projection light. The material is developed and cured and the front side is optionally protected with a sealant layer. In a second embodiment, a light source is directed against the lens array and used to charge the front screen surface, which is then layered with a material which adheres to the screen only in the non-transmissive areas.

A compact laser package with integrated temperature control is disclosed. In one embodiment, the compact laser package that includes a housing, a window through the housing, a laser emitter disposed in the housing, and an active temperature control device disposed in the housing. The laser emitter is disposed on the active temperature control device and aligned such that optical signals generated by the laser emitter can be emitted through the window without a waveguide. Additionally, the housing has an outline similar to that of a transistor-can. Temperature measuring device and laser power detection device may also be integrated within the laser package.

Exemplary embodiments of the present invention selectively adapt the pad architecture on bi-directional opto-electronic transceiver modules to connect to legacy unidirectional ports, panels and the like. This allows the bi-directional module to function correctly when connected to either a unidirectional or a bi-directional port. Conversely, exemplary embodiments also selectively adapt the pad architecture on bi-directional patch panels or ports to connect to legacy unidirectional optoelectronic transceiver modules. This allows the port to function correctly when either a bi-directional or a unidirectional transceiver is connected to it.

A system and method for testing the jitter tolerance and signal attenuation tolerance of an optoelectronic device is disclosed. The system includes a generation circuit, delay circuit and comparison circuitry. A first sequence of bits is generated, delayed, and sent to the optoelectronic device. The optoelectronic device receives the bits and retransmits them as a second sequence to the comparison circuitry, which compares the two bit sequences to determine a bit error rate. The bit error rate is then used to determine the jitter tolerance and, in an alternate embodiment, the signal attenuation tolerance of the optoelectronic device being tested.
