US Patent:

59332603, Aug 3, 1999

Filed:

Apr 25, 1997

Appl. No.:

8/846027

Inventors:

Xiaofan Cao - San Mateo CA
Yu Zheng - Sunnyvale CA

Assignee:

Oplink Communications, Inc. - San Jose CA

International Classification:

H04J 1402

US Classification:

359124

Abstract:

A system and method for separating a component signal having a predetermined wavelength from a signal carried over a range of wavelengths is disclosed. The system comprises a first filter for transmitting light of the predetermined wavelength. The component signal is reflected rather than transmitted. The system further comprises a second filter for transmitting light of a second predetermined wavelength. The second filter is in the transmission direction from the first filter. Thus, the component signal is separated by transmission by the first filter and reflection from the second filter.

Appl. No.:

8/816089

Inventors:

Xiaofan Cao - San Mateo CA
Yu Zheng - Sunnyvale CA

Assignee:

Oplink Communications, Inc. - San Jose CA

International Classification:

H04B 1004

US Classification:

359132

Abstract:

A system and method for monitoring a wavelength of light produced by a light source is disclosed. The system and method comprise a diffractor for diffracting the light. A first portion of the light is transmitted without diffraction and has a propagation direction. A second portion of the light has a predetermined wavelength and is diffracted through a predetermined angle from the propagation direction. The system also comprises a plurality of filters at the predetermined angle from the propagation direction from the diffractor. The filters transmit light of the predetermined wavelength. The system also comprises a plurality of photodiodes. Each photodiode provides a signal corresponding to an intensity of light and corresponds to a one of the plurality of filters. Each photodiode is placed behind a corresponding filter. According to the system and method disclosed, the system and method monitor the wavelength without significant interruption of the beam.

Appl. No.:

8/906284

Inventors:

Steven Guoxin Zhu - Fremont CA
Yu Zheng - Sunnyvale CA

Assignee:

Oplink Communications, Inc. - San Jose CA

International Classification:

G02B 702
G02B 636

US Classification:

359819

Abstract:

A system and method for providing an optical collimator is disclosed. The collimator includes a lens, a pigtail, and a holder. The method and system include aligning the lens and the pigtail, affixing a position of the lens with respect to a position of the pigtail, and placing the lens and the pigtail in the holder. The alignment is carried out in three dimensions.

Inventors:

- Mountain View CA, US
Mishika Vora - Hayward CA, US
Tiffany Washburn - Sunnyvale CA, US
Yu Zheng - Milpitas CA, US
Sandra Lennie - San Mateo CA, US

International Classification:

G05D 1/02
G05D 1/00
G06K 9/32

Abstract:

Aspects of the disclosure relate to evaluating pullovers for autonomous vehicles. In one instance, a set of potential pullover locations within a predetermined distance of a destination may be identified. Whether any of the potential pullover locations of the set include one or more of a plurality of predetermined types of regions of interest where a vehicle should not park for an extended period of time may be determined. A pullover location is identified based on the determination. The identified pullover location may be compared to a pullover location identified by autonomous vehicle control software in order to evaluate the pullover location identified by the autonomous vehicle control software.
