Abstract:
An add/drop node is disclosed. The add/drop node includes a first filter configured to receive a light beam having a plurality of channels. The first filter is also configured to direct channels having wavelengths falling within a plurality of first wavelength bands to a transition waveguide. The add/drop node also includes a second filter configured to receive the channels directed to the transition waveguide. The second filter is configured to direct channels having wavelengths falling within a plurality of second wavelength bands to a drop waveguide. The first filter and/or the second filter can be tunable.

Assignee:
Kotura, Inc. - Monterey Park CA
International Classification:
G02B006/00
G02B006/16
H01L021/00
H01J003/14
US Classification:
385130, 438 22, 385140, 385147, 385 11, 250216
Abstract:
An optical device includes a ridge waveguide defined by a ridge extending from a slab of a light transmitting medium. The optical device also includes trenches extending into the slab of light transmitting medium on opposing sides of the ridge. At least one of the trenches is associated with a trench displacement that tapers from a first displacement to a second displacement. The trench displacement is the distance between the ridge and the side of a trench closest to the ridge. The optical device also includes at least one electrical contact positioned in at least one of the trenches.

Waveguide Tap Monitor

US Patent:
6885795, Apr 26, 2005
Filed:
May 31, 2002
Appl. No.:
10/161208
Inventors:
Shih-Hsiang Hsu - Pasadena CA, US
Dazeng Feng - Arcadia CA, US
Cheng-Chih Kung - Alhambra CA, US
Xiaoming Yin - Pasadena CA, US
Trenton Gary Coroy - Rancho Cucamunga CA, US
Assignee:
Kotusa, Inc. - Monterey Park CA
International Classification:
G02B006/26
US Classification:
385 48, 385 88
Abstract:
An optical component is disclosed. The optical component includes a tap waveguide and a primary waveguide positioned on a base. The tap waveguide is configured to receive a portion of a light signal traveling along the primary waveguide. The portion of the light signal received by the tap waveguide is the tapped portion of the light signal. A direction changing region is configured to receive the tapped portion of the light signal from the tap waveguide and to direct the tapped portion of the light signal travels away from the base. A light sensor is configured to receive the tapped portion of the light signal from the direction changing region.

Optical Component Having Waveguides Extending From A Common Region

View page
US Patent:
6921490, Jul 26, 2005
Filed:
Sep 6, 2002
Appl. No.:
10/236505
Inventors:
Wei Qian - Torrance CA, US
Dazeng Feng - Arcadia CA, US
Dawei Zheng - Los Angeles CA, US
Joan Yiqiong Fong - San Marino CA, US
Zhian Shao - Torrance CA, US
Xiaoming Yin - Pasadena CA, US
Assignee:
Kotura, Inc. - Monterey Park CA
International Classification:
B29D011/00
US Classification:
216 24
Abstract:
A method of forming an optical component includes forming a first mask on an optical component precursor. The first mask is formed with a plurality of waveguide portions extending from a common portion. Each waveguide portion is positioned so as to protect a waveguide region of the optical component precursor where a waveguide is to be formed. The method also includes forming a second mask between waveguide portions of the first mask. The resistance of the second mask to etching varies along at least one dimension of the second mask.

Wafer Level Testing Of Optical Components

US Patent:
6947622, Sep 20, 2005
Filed:
Jun 27, 2002
Appl. No.:
10/186187
Inventors:
Liwei Wang - Arcadia CA, US
Dazeng Feng - Arcadia CA, US
Xiaoming Yin - Pasadena CA, US
Trenton Gary Coroy - Rancho Cucamonga CA, US
Assignee:
Kotura, Inc. - Monterey Park CA
International Classification:
G02B006/26
US Classification:
385 15, 372 50, 359629
Abstract:
An optical device having one or more optical components is disclosed. A waveguide extends from an optical component to a testing port configured to receive a light signal from a position over the optical device and to insert the light signal into the waveguide. In some instances, the testing port is configured to receive a light signal from the waveguide and to direct the light signal to a location over the optical device. The optical device can be positioned on a wafer before being separated from the wafer. The waveguide can extend from an optical component over the perimeter of the optical device such that the testing ports are located outside the perimeter of the optical device.

Optical Component Having Reduced Interference From Radiation Modes

US Patent:
6970611, Nov 29, 2005
Filed:
Aug 27, 2003
Appl. No.:
10/649044
Inventors:
Frederik Marcel Van Der Vliet - Pasadena CA, US
Joan Fong - San Marino CA, US
Dazeng Feng - Arcadia CA, US
Assignee:
Kotura, Inc. - Monterey Park CA
International Classification:
G02B006/12
US Classification:
385 14, 385130, 385147, 257 3
Abstract:
An optical component includes an optical device positioned between isolation channels. The isolation channels are configured to at least partially isolate different regions of the optical component from one another. The optical component also includes at least one light absorbing region positioned so as to intercept light traveling in a direction that would take the light between the optical device and an isolation channel.

High Speed Optical Phase Modulator

View page
US Patent:
7394948, Jul 1, 2008
Filed:
Jun 7, 2005
Appl. No.:
11/146898
Inventors:
Dawei Zheng - Alhambra CA, US
Dazeng Feng - Arcadia CA, US
Anthony Kewitsch - Santa Monica CA, US
George Rakuljic - Santa Monica CA, US
Assignee:
Kotura, Inc. - Monterey Park CA
International Classification:
G02F 1/035
G02B 6/26
G02B 6/42
US Classification:
385 3, 385 2, 385 40
Abstract:
An optical device includes a phase modulator having a waveguide on a substrate. The phase modulator also includes an n-type region having a proximity to a p-type region that causes formation of a depletion region when a bias is not applied to the modulator. The depletion region is at least partially positioned in the light signal carrying region of the waveguide. The phase modulator is tuned by applying a reverse bias to the phase modulator. The reverse bias changes the size of the depletion region.
