Patent number: 8841591Abstract: Systems, methods and devices are implemented for optical imaging. In one embodiment of the present disclosure, an optical imaging apparatus utilizes a laser-based coherent light source, and an optical device to pass grated light along an illumination direction from the laser-based coherent light source toward an object. Additionally, an illumination modulator is provided for changing angles at which the light, moving toward the object plane, reaches the object plane, and the light reaches the object plane at different angles. Further, the apparatus can include circuitry to process image-based data in response to and based on the light reaching the object plane at different angles for a user-viewable image of an object in proximity of the object plane.Type: GrantFiled: April 4, 2012Date of Patent: September 23, 2014Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Jeffrey P.

Patent number: 7177496Abstract: The present invention provides a method and apparatus for optical spectral power monitoring that employ a time-division-multiplexed detection scheme. The optical spectral power monitoring apparatus of the present invention uses a wavelength-dispersing means such as a diffraction grating to separate a multi-wavelength optical signal into multiple spectral channels and an array of beam-manipulating elements positioned to correspond with the spectral channels. The beam-manipulating elements are individually controllable so as to direct the spectral channels into an optical detector in a time-division-multiplexed sequence. The optical spectral power monitoring apparatus may further employ a polarization diversity scheme, thereby becoming polarization insensitive. This enables the apparatus of the present invention to enhance spectral resolution, while providing improved accuracy in optical spectral power detection.Type: GrantFiled: December 27, 2001Date of Patent: February 13, 2007Assignee: Capella Photonics, Inc.Inventors: Pavel G. Polynkin, Mark H. Garrett, Jeffrey P. Wilde

Patent number: 7164859Abstract: A novel wavelength routing apparatus is disclosed, which uses a diffraction grating to separate a multi-wavelength optical signal from an input port into multiple spectral channels; a channel-interleaving assembly (e.g., an array of prisms) to interleave the spectral channels into two channel groups; and an “augmented relay system” to relay the interleaved channel groups onto two separate arrays of channel micromirrors, respectively. The channel micromirrors are individually controllable and pivotable to reflect the spectral channels into multiple output ports. As such, the inventive wavelength routing apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports.Type: GrantFiled: August 28, 2002Date of Patent: January 16, 2007Assignee: Capella Photonics, Inc.Inventors: Karl Arnold Belser, Masud Mansuripur, Jeffrey P.

Patent number: 7057796Abstract: This invention provides a wavelength-separating-routing (WSR) apparatus that uses a diffraction grating to separate a multi-wavelength optical signal by wavelength into multiple spectral channels that are communicated to an array of channel micromirrors, and which includes a micromirror position sensing unit to monitor the position of each of the channel micromirrors. The micromirror position sensing unit may include an array of position sensitive detectors or split detectors, which each receive a diverted fraction of one of the reflected spectral channels.Type: GrantFiled: September 3, 2003Date of Patent: June 6, 2006Assignee: Capella Photonics, Inc.Inventor: Jeffrey P.

Patent number: 6879750Abstract: This invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating to separate a multi-wavelength optical signal by wavelength into multiple spectral channels, which are then focused onto an array of corresponding channel micromirrors. The channel micromirrors are individually controllable and continuously pivotable to reflect the spectral channels into selected output ports. As such, the inventive WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values.Type: GrantFiled: December 22, 2003Date of Patent: April 12, 2005Assignee: Capella Photonics, Inc.Inventors: Tai Chen, Jeffrey P.

Patent number: 6850475Abstract: An optical data storage system utilizes optical fibers for transfer of information to and from storage media. The storage media includes magneto-optical storage disks. The optical fibers are single-mode polarization maintaining optical fibers. A single frequency laser diode provides a source of polarized light. Accordingly, a polarization state conveyed by the polarization maintaining optical fiber is accurately reproduced with reduced noise, as compared to use of a Fabry-Perot laser diode.Type: GrantFiled: June 26, 1997Date of Patent: February 1, 2005Assignee: Seagate Technology, LLCInventors: John F.
