Assignee:

Uniphase Corporation - San Jose CA

International Classification:

G02B 612

US Classification:

385 14

Abstract:

An integrated optical transmitter for use in an optical system has an optical head assembly with an optical beam generator for providing an optical beam and a lens assembly collecting the optical beam and generating therefrom a formed optical beam. Interface optics receives the formed optical beam and provides optical coupling so as to minimize insertion loss to the optical beam. Also included is an optical modulator for receiving the optical beam from the interface optics and for providing a modulated optical beam in response to received modulation signals. The optical modulator is coupled to the interface optics to be in a fixed relationship therewith.

International Classification:

G01N 2125

US Classification:

356326, 356419, 250226

Abstract:

A multi-channel wavelength monitor is described that includes a dispersive element that is positioned in an optical path of an incident optical beam having a plurality of wavelengths. The dispersive element disperses the optical beam into a plurality of optical beams that simultaneously propagate in a plurality of optical paths, where each of the plurality of optical beams has one of the plurality of wavelengths. An optical filter is positioned to intercept each of the plurality of optical paths at a plurality of locations. The optical filter substantially passes a respective one of the plurality of optical beams at a respective one of the plurality of locations and substantially blocks the other optical beams. A plurality of optical detectors is positioned adjacent to the optical filter in a direction of propagation of the plurality of optical beams. A respective one of the plurality of optical detectors is positioned in a respective one of the plurality of optical paths.

Abstract:

A micro-optical delay element for a time-division multiplexing scheme is disclosed wherein two light beams are provided to a beam splitter/combiner (BS/C) in the absence of optical fibre. At least one beam exiting a modulator is collimated and reaches the (BS/C) unguided as a substantially collimated beam. This obviates a requirement for polarization controllers and polarization maintaining optical fiber.

International Classification:

G02B 6255

US Classification:

385 95

Abstract:

An optical fiber having a core, a cladding layer, a buffer layer, and a midsection for forming a hermetic seal to the fiber. First and second sections of a length of the optical fiber are separated by the midsection that includes a jacket hermetically sealed to the fiber, the jacket having a hermetically sealable outer surface. First and second stress relief joints are formed between the jacket and the buffer layers of the first and second sections of the length of the fiber. A method is disclosed for fabricating the optical fiber having a hermetically sealable section.

Abstract:

An integrated optical transmitter for use in an optical system includes an optical head assembly having an optical beam generator for providing an optical beam and a lens assembly for collecting the optical beam and generating therefrom a formed optical beam. Interface optics receive the formed optical beam for coupling the beam to a modulator so as to reduce nsertion loss to the optical beam. The optical modulator receives the optical beam from the interface optics and provides a modulated optical beam in response to received modulation signals. The optical modulator is coupled to the interface optics to be in a fixed relationship therewith. The integrated optical transmitter can include a means for sampling the optical beam and controlling the temperature of and/or the current supplied to the optical beam generator for controlling the wavelength of the optical transmitter. The optical head assembly and the modulator can be compliantly mounted to a mounting surface reducing the effects of thermal stress on the performance of the optical transmitter.
