Filed:

Oct 30, 2002

Appl. No.:

10/283476

Inventors:

Frank H. Peters - San Jose CA

Assignee:

Infinera Corporation - Sunnyvale CA

International Classification:

H01S 500

US Classification:

372 50, 372 45

Abstract:

Electrical isolation regions are formed between adjacently disposed electro-optical components integrated in a monolithic semiconductor photonic chip, such as an EML or PIC chip. A bias, V , is applied to the isolation region so that any parasitical current path developed between adjacent active or passive optical components, now separated by an isolation region, is established through the electrical isolation region and clamped to the bias, V. The applied bias, V , may be a positive bias, a negative bias, or a zero or a ground bias. The electrical isolation regions are formed by spatial current blocking regions formed at adjacent sides of the electrical isolations region transverse to a direction of light propagation through the optical components, or between the electrical isolation regions and adjacent optical components. The spatial current blocking regions may be comprised of a pair of spatially disposed trenches or ion implanted regions or high resistance implanted regions.

Appl. No.:

10/040167

Inventors:

Frank H. Peters - San Jose CA, US
Michael H. Leary - Fremont CA, US
Yoon-Kyu Song - San Jose CA, US

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

H01S 500

US Classification:

372 46, 372 45

Abstract:

An optoelectronic device such as a vertical cavity surface emitting laser (VCSEL) includes a tunnel junction that conducts a current of holes tunneling into an active region. Tunneling in a selected area of the tunnel junction is disabled to form a current blocking region that confines the current to desired regions. Tunneling can be disabled in the selected area using techniques including but not limited to implanting or diffusing dopants, disrupting crystal structure, or etching to remove part of the tunnel junction.

Appl. No.:

10/283475

Inventors:

Frank H. Peters - San Jose CA, US
Radhakrishnan L. Nagarajan - Cupertino CA, US

International Classification:

H01S003/04

US Classification:

372 36, 372 34, 372 50, 385 14

Abstract:

Photonic integrated circuits (PIC) semiconductor chips are provided with thermal isolation and/or heat dissipation structures between integrated optical components in the PIC chip, particularly integrated active optical components. These structures may also serve as a ground path for electrical circuitry on the PIC chip. An important function is the enhanced thermal isolation from, or dissipation of heat from, between adjacent or neighboring optical components in the PIC so that required spacing between adjacent optical components can be made even less than the thickness of the substrate thereby realizing a more compact optical component array on the monolithic PIC chips.

Abstract:

A method of electrically isolating and operating electro-optical components integrated in a monolithic semiconductor photonic chip, such as an EML or PIC chip. A bias, V, is applied to the isolation region so that any parasitical current path developed between adjacent active or passive optical components, now separated by an isolation region, is established through the electrical isolation region and clamped to the bias, V. The applied bias, V, may be a positive bias, a negative bias, or a zero or a ground bias.
