Appl. No.:

09/920795

Inventors:

Alan Michael Braun - New Brunswick NJ
Joseph Hy Abeles - East Brunswick NJ
Robert Amantea - Manalapan NJ

Assignee:

Sarnoff Corporation - Princeton NJ

International Classification:

G02B 626

US Classification:

385 50, 385 14, 385 24, 385 27, 398 82, 398 42, 398 45, 398 48

Abstract:

One embodiment of the present invention is an exemplary wavelength selective optical coupling device. This exemplary device includes two waveguides, a ring or disc resonator, and resonator coupling elements. The waveguides are disposed on top of a substrate, not in contact with each other. The waveguides may transmit multiple wavelengths of light. The ring or disc resonator includes a dielectric member which extends parallel to the top of the substrate and overlaps, without contacting, the waveguides. The resonator is sized to resonate at a subset of resonant wavelengths. The resonator coupling elements couple the resonator to the substrate. The resonator coupling elements may include a bridge coupled to the top surface of the substrate and electrically coupled to control circuitry within the substrate. A waveguide coupling signal from the control circuitry causes the bridge to deform, translating the resonator up and down, thereby intermittently coupling and decoupling the waveguides.

Inventors:

- Menlo Park CA, US
Joey J. Michalchuk - Lambertville NJ, US
Seth Charles Caliga - Lafayette CO, US
Alan M. Braun - Princeton NJ, US

International Classification:

G02B 6/122

Abstract:

The disclosure describes vacuum cell assemblies that integrate a vacuum envelope with a photonic integrated circuit (PIC). Walls of the vacuum envelope are coupled to the PIC, such as through anodic bonding, so that the PIC forms at least one wall of the vacuum envelope and provides an optically accessible medium and surface for transmitting and distributing light into various cavities of the vacuum envelope through one or more nonplanar waveguides. A surface of the PIC may include a material that is compatible with a material of the walls of the vacuum envelope, such as a silicon-based vacuum envelope bonded to a silicon nitride or amorphous silicon surface of the PIC. Each waveguide may include a bridge structure that forms a planar surface for tightly bonding with the vacuum envelope and preserves properties of the transmitted light between opposing sections of the waveguide.
