Abstract:

An optoelectronic mounting structure is provided that may be used in conjunction with an optical transmitter, receiver or transceiver module. The mounting structure may be a flexible printed circuit board. Thermal vias or heat pipes in the head region may transmit heat from the mounting structure to the heat spreader. The heat spreader may provide mechanical rigidity or stiffness to the heat region. In another embodiment, an electrical contact and ground plane may pass along a surface of the head region so as to provide an electrical contact path to the optoelectronic devices and limit electromagnetic interference. In yet another embodiment, a window may be formed in the head region of the mounting structure so as to provide access to the heat spreader. Optoelectronic devices may be adapted to the heat spreader in such a manner that the devices are accessible through the window in the mounting structure.

Abstract:

An optical power control system is provided that may be used in connection with an optical transmitter, receiver or transceiver module. The optical power control system comprises: (1) an array of optoelectronic devices; (2) an array of optical elements; (3) the array of optical elements optically aligned to the array of optoelectronic devices in such a manner that one or more optical elements is optically aligned to one or more optoelectronic devices; (4) a light-receiving device; and (5) a reflector proximate to the array of optical elements, the reflector optically orientated with the array of optoelectronic devices and the light-receiving device such that some emission from at least one optoelectronic device is reflected on at least a portion of the light-receiving device. The optical elements may be optical fibers and may be packaged in a ferrule. The light-receiving device may be a photo-detector or a light pipe. A feedback loop connects the light-receiving device to the array of optoelectronic devices so as to adjust the output of the array of optoelectronic devices in response to the emission detected by the light-receiving device. The reflector scatters the emission from the optoelectronic device, and it may be adapted to a bottom surface of a ferrule. In another embodiment, optical resin is dispensed proximate to the array of optoelectronic devices and light-receiving device. Emission from at least one optoelectronic device is reflected onto the light-receiving device by the optical resin.

International Classification:

US Classification:

385 52

Abstract:

A fiber alignment apparatus includes a micro-machined nickel spring that captures and locks arrays of single mode fibers into position. The design consists of a movable nickel leaf shaped spring and a fixed pocket where fibers are held. The fiber is slid between the spring and a fixed block, which tensions the spring. When the fiber reaches the pocket, it automatically falls into the pocket and is held by the pressure of the leaf spring.
