US Patent:

7366380, Apr 29, 2008

Filed:

Apr 18, 2005

Appl. No.:

11/109210

Inventors:

Mark Peterson - San Diego CA, US
Mark Harrison - Escondido CA, US

Assignee:

Luxtera, Inc. - Carlsbad CA

International Classification:

G02B 6/26
G02B 6/42

US Classification:

385 47

Abstract:

Planar lightwave circuit (PLC) connects optical fibers to the top of an optical or optoelectronic device or optical or optoelectronic integrated circuit. Light propagating through optical fibers is directed to optical waveguides disposed on optical devices. The optical fibers can be in the form of individual fibers, a fiber ribbon or a fiber array. Fiber optic cables can be plugged into a ferrule attached to the PLC. The PLC can also include optical components integrated into the optical path between the optical fibers and the optical device.

US Classification:

385 14, 385 15, 385 31, 361767

Abstract:

A transceiver on a CMOS chip including optical and optoelectronic devices, and electronic circuitry may be operable to communicate optical signals between the CMOS chip and optical fibers coupled to the CMOS chip via a semiconductor laser and one or more photodetectors. The optical and optoelectronic devices may include waveguides, modulators, multiplexers, switches, and couplers. The photodetector may be integrated in the CMOS chip. The photodetector and the semiconductor laser may be mounted on the CMOS chip. The optical signals may be communicated out of and in to a top surface of the CMOS chip. A transceiver on a CMOS chip including optical and optoelectronic devices, and electronic circuitry, may be operable to communicate optical signals between the CMOS chip and optical fibers coupled to the CMOS chip via grating couplers. The optical signals may be communicated out of and in to a top surface of the CMOS chip.

US Classification:

385 14, 385 15, 385 31, 361767

Abstract:

A transceiver comprising a plurality of CMOS chips may be operable to communicate an optical source signal from a semiconductor laser into a first CMOS chip via optical couplers. The optical source signal may be used to generate first optical signals that are transmitted from the first CMOS chip to optical fibers coupled to the first CMOS chip via one or more optical couplers. Second optical signals may be received from the optical fibers and converted to electrical signals via photodetectors in the first CMOS chip. The optical source signal may be communicated from the semiconductor laser into the first CMOS chip via optical fibers in to a top surface and the first optical signals may be communicated out of a top surface of the first CMOS chip. The electrical signals may be communicated to at least a second of the plurality of CMOS chips comprising electronic devices.
