Resonant Optical Filters

View page
US Patent:
6865317, Mar 8, 2005
Filed:
Feb 16, 2001
Appl. No.:
09/788300
Inventors:
Kerry J. Vahala - San Gabriel CA, US
Peter C. Sercel - Pasadena CA, US
David W. Vernooy - Monrovia CA, US
Oskar J. Painter - Pasadena CA, US
Guido Hunziker - Monrovia CA, US
Assignee:
Xponent Photonics Inc - Monrovia CA
International Classification:
G02B006/26
US Classification:
385 30, 385 27, 385 50
Abstract:
A resonant optical filter includes first and second transmission waveguides and a resonator (including one or more evanescently coupled resonator segments). The resonator supports at least one circumferential resonant mode and is evanescently coupled to the waveguides. An optical signal entering the filter through a waveguide and substantially resonant with the resonator is transferred to the other waveguide, while an optical signal entering the filter and substantially non-resonant with the resonator remains in the same waveguide. Multiple resonator segments may be formed on a common resonator fiber and positioned for enabling coupling between them, resulting in a tailored frequency filter function. The resonators may include alignment structure(s) (flanges, grooves, etc) for enabling passive positioning and/or supporting first and second transmission waveguides, such as optical fiber tapers. Structures may also be provided for suppressing undesired optical modes and/or resonances associated with the resonators and/or alignment structures on the resonator fiber.

Cylindrical Processing Of Optical Media

US Classification:
385 39, 385 30, 385 43, 385123
Abstract:
A method for cylindrical processing of an optical medium, including optical fiber and optical materials of substantially cylindrical form. The method of the preferred embodiments includes the steps of rotating an optical medium about a longitudinal relative rotation axis thereof relative to a processing tool; spatially selectively applying the processing tool to a portion of a surface of the optical medium in operative cooperation with relative rotation of the optical medium and the processing tool, thereby producing a patterned (i. e. , spatially selective) structural alteration of the optical medium, the pattern including altered, differentially-altered and unaltered portions of the optical medium. Specialized techniques for spatially selectively generating the structural alteration may include masking/etching, masking/deposition, machining or patterning with lasers or beams, combinations thereof, and/or functional equivalents thereof.

Kerry J. Vahala - San Gabriel CA, US
David W. Vernooy - Monrovia CA, US
Guido Hunziker - Monrovia CA, US
Robert B. Lee - Monrovia CA, US
Oskar J. Painter - Pasadena CA, US
Assignee:
Xponent Photonics Inc. - Monrovia CA
International Classification:
G02B006/26
US Classification:
385 30, 385 1, 385 15, 385 27, 385 40, 385 48, 385 50
Abstract:
An alignment device includes an alignment member with one or more waveguide-alignment grooves, resonator alignment grooves, and/or an alignment groove for a second optical element such as a modulator. The various alignment grooves reliably establish and stably maintain evanescent optical coupling between the optical elements positioned therein. A method for assembling a resonant optical power control device may include: fabricating an alignment member with the alignment grooves; positioning and securing the optical elements in corresponding alignment grooves for optical coupling therebetween. Alignment grooves in the substrate and/or in one or more of the optical elements are fabricated at proper depths and positions and preferably with mating grooves and/or flanges to enable optical coupling without extensive active alignment procedures.

Fiber-Ring Optical Resonators

US Patent:
6891997, May 10, 2005
Filed:
Feb 16, 2001
Appl. No.:
09/788331
Inventors:
Peter C. Sercel - Pasadena CA, US
Kerry J. Vahala - San Gabriel CA, US
Guido Hunziker - Altadena CA, US
David W. Vernooy - Sierra Madre CA, US
Robert B. Lee - Pasadena CA, US
Assignee:
Xponent Photonics Inc. - Monrovia CA
International Classification:
G02B006/26
US Classification:
385 30, 385 15, 385 28, 385 43, 385 50
Abstract:
A fiber-ring optical resonator comprises a transverse segment of an optical fiber differing from adjacent segments in at least one physical property (e. g. , diameter, density, refractive index, chemical composition, etc) so that it may support a resonant circumferential optical mode and enable evanescent optical coupling between the circumferential mode and an optical mode of a second optical element. The resonator may be fabricated with alignment structure(s) for enabling passive alignment of the second optical element for evanescent coupling, and/or with structure for suppressing undesired modes and/or resonances. A fiber-ring resonator may form a portion of a resonant optical filter or modulator. A plurality of optically-coupled fiber-ring resonators (formed on one or more fibers) may provide tailored spectral properties. Spatially-selective techniques for forming a fiber-ring resonator may include masking/etching, masking/deposition, laser machining, laser patterning, combinations thereof, and/or functional equivalents thereof.

Polarization-Engineered Transverse-Optical-Coupling Apparatus And Methods

US Patent:
6907169, Jun 14, 2005
Filed:
Oct 30, 2002
Appl. No.:
10/284041
Inventors:
Kerry J. Vahala - San Gabriel CA, US
Peter C. Sercel - Pasadena CA, US
Oskar J. Painter - Pasadena CA, US
David W. Vernooy - Sierra Madre CA, US
David S. Alavi - Eugene OR, US
Assignee:
Xponent Photonics Inc - Monrovia CA
International Classification:
G02B006/26
US Classification:
385 50, 385 11, 385 28, 385 43
Abstract:
An optical signal may be received into orthogonal linearly polarized modes of a transmission optical waveguide, the transmission waveguide including first and second transverse-coupling segments thereof. Optical signal polarized along one polarization direction may be substantially completely transferred from the transmission waveguide into a first transverse-coupled waveguide, the first transverse-coupled waveguide being optically transverse-coupled to the first transverse-coupling segment of the transmission waveguide. Optical signal polarized along the other polarization direction may be substantially completely transferred from the transmission waveguide into a second transverse-coupled waveguide, the second transverse-coupled waveguide being optically transverse-coupled to the second transverse-coupling segment of the transmission waveguide. The optical signals carried by the first and second transverse-coupled waveguides may be combined into a single waveguide. The polarization directions of the transmission waveguide may be rotated about 90 between the first and second transverse-coupling segments.

Resonant Optical Modulators

US Patent:
7106917, Sep 12, 2006
Filed:
Dec 21, 2001
Appl. No.:
10/037146
Inventors:
Oskar J. Painter - Pasadena CA, US
Peter C. Sercel - Pasadena CA, US
Kerry J. Vahala - San Gabriel CA, US
David W. Vernooy - Sierra Madre CA, US
Guido Hunziker - Altadena CA, US
Assignee:
Xponent Photonics Inc - Monrovia CA
International Classification:
G02F 1/35
US Classification:
385 2, 385 1, 385 27, 385 34
Abstract:
A resonant optical modulator comprises a transmission fiber-optic waveguide, a circumferential-mode optical resonator transverse-coupled thereto, a modulator optical component transverse-coupled to the circumferential-mode resonator, and a modulator control component. A control signal applied to the modulator optical component through the modulator control component alters the round-trip optical loss of the circumferential-mode resonator, thereby altering the transmission of a resonant optical signal through the transmission fiber-optic waveguide. The modulator optical element may comprise an open waveguide or a closed waveguide (i. e. , resonator). The resonator round-trip optical loss may be altered by altering the optical absorption/scattering of the modulator optical component, by altering the amount of optical power transfer between the resonator and the modulator optical component, or by altering an optical resonance frequency of a resonant modulator optical component.
