Assignee:

Triquint Technology Holding Co. - Hillsboro OR

International Classification:

H01S 5042

US Classification:

372 3802

Abstract:

An uncooled, through-hole configured laser module adapted to receive and transmit RF signals to a laser at bandwidths from direct current (DC) to about ten gigahertz. The laser module incorporates an option for two pin-out configurations. One pin-out configuration has one ground pin and one signal pin for operation at about one gigabit/second or one gigahertz. The second high performance pin-out uses two ground pins and one signal pin for operation up to about ten gigabit/second or ten gigahertz.

Triquint Technology Holding Co. - Hillsboro OR

International Classification:

G01B 902

US Classification:

356450

Abstract:

The present invention is directed toward a monitoring and control system for an optical system. In one aspect of the present invention the system may include an interferometer that splits an input beam into a transmitted portion and a reflected portion. The interferometer introduces a path length difference between at least a segment of the transmitted and reflected portions that recombine to form an output beam having an intensity that varies as a function of wavelength of the input beam.

International Classification:

G02B 636

US Classification:

385 92

Abstract:

An optical transceiver assembly for use in a bidirectional system includes a beam splitter to direct an incoming signal to a photodiode. An outgoing signal from a laser diode is partially transmitted and partially reflected by the splitter. The reflected signal, which may reach the photodiode, constitutes crosstalk which is reduced by orienting the polarization direction of the splitter essentially parallel to that of the outgoing signal from the laser diode. In another embodiment, which enhances coupling efficiency, a single element asphere lens is positioned between the laser diode and the splitter.

US Classification:

359159

Abstract:

An optical transceiver assembly for use in a bidirectional system includes an optical fiber to which an outgoing optical signal is coupled. To reduce reflections from the end face of the fiber, the end face is beveled at an acute angle. phi.

Abstract:

An optical transceiver assembly for use in a bidirectional system includes a beam splitter to direct an incoming signal to a photodiode. An outgoing signal from a laser diode is partially transmitted and partially reflected by the splitter. The reflected signal, which may reach the photodiode, constitutes crosstalk which is reduced by means of a cavity positioned to receive the reflected signal and an oblique surface within the cavity adapted to prevent much of the reflected signal from reaching the photodiode.
