Patent number: 8289521Abstract: A fiber-optic sensor includes an optical fiber coil and a laser source optically coupled to the coil. Light from the source is transmitted to the coil as a first optical signal and a second optical signal counter-propagating through the coil. The optical paths of the first optical signal and the second optical signal are substantially reciprocal with one another and the first optical signal and the second optical signal are combined together after counter-propagating through the coil to generate a third optical signal. The laser source is frequency-modulated or can have a coherence length longer than a length of the coil.Type: GrantFiled: February 15, 2011Date of Patent: October 16, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Stephane Blin, Michel J. F. Digonnet, Gordon S. Kino, Seth Lloyd

Patent number: 7911619Abstract: A fiber-optic sensor includes an optical fiber coil and a laser source optically coupled to the coil. Light from the source is transmitted to the coil as a first signal propagating along the coil in a first direction and a second signal propagating along the coil in a second direction opposite to the first direction. The optical paths of the first signal and the second signal are substantially reciprocal with one another and the first signal and the second signal are combined together after propagating through the coil to generate a third signal. The laser source is frequency-modulated or can have a coherence length longer than a length of the coil.Type: GrantFiled: November 14, 2008Date of Patent: March 22, 2011Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Stéphane Blin, Michel J.

Patent number: 7471710Abstract: A narrow linewidth semiconductor laser device has a semiconductor laser and a low noise current source operatively connected to the laser with the current source being adapted to prevent degradation of the laser's frequency noise spectrum. An optical frequency discriminator provides an error signal representative of the laser's optical frequency and a control circuit has a feedback network that provides a frequency feedback signal that is adapted to the frequency noise spectrum of the frequency discriminator and to the laser's frequency noise spectrum and tuning response. The control circuit also has a sequencer to automatically enable frequency locking of the laser on the frequency reference of the optical frequency discriminator. An enclosure encloses the frequency discriminator to isolate the frequency discriminator from external perturbations.Type: GrantFiled: December 23, 2005Date of Patent: December 30, 2008Assignee: Teraxion Inc.Inventors: Jean-François Cliche, Michel Tetu, François Baribeau, Stéphane Blin, Martin Guy

Publication number: 20080030741Abstract: An optical sensor includes a directional coupler comprising at least a first port, a second port, and a third port. The first port is in optical communication with the second port and with the third port such that a first optical signal received by the first port is split into a second optical signal that propagates to the second port and a third optical signal that propagates to the third port. The optical sensor further includes a photonic bandgap fiber having a hollow core and an inner cladding generally surrounding the core. The photonic bandgap fiber is in optical communication with the second port and with the third port. The second optical signal and the third optical signal counterpropagate through the photonic bandgap fiber and return to the third port and the second port, respectively. The photonic bandgap fiber has a phase thermal constant S less than 8 parts-per-million per degree Celsius.Type: ApplicationFiled: June 28, 2007Publication date: February 7, 2008Inventors: Michel Digonnet, Hyang Kim, Stephane Blin, Vinayak Dangui, Gordon Kino

Publication number: 20060159135Abstract: There is provided a narrow linewidth semiconductor laser device comprising a semiconductor laser and a low noise current source operatively connected to the laser for supplying current thereto, the current source being particularly adapted to prevent a significant degradation of the frequency noise spectrum of the laser. The laser device also has an optical frequency discriminator providing an error signal representative of the optical frequency of the laser. The laser device also has control means having a feedback network for providing a frequency feedback signal. The feedback network is particularly adapted to the frequency noise spectrum of the frequency discriminator, the frequency noise spectrum of the laser and the tuning response of the laser. The control means is also provided with sequencing means for allowing to automatically enable frequency locking of the laser on the frequency reference of the optical frequency discriminator.Type: ApplicationFiled: December 23, 2005Publication date: July 20, 2006Applicant: Teraxion Inc.Inventors: Jean-Francois Cliche, Michel Tetu, Francois Baribeau, Stephane Blin, Martin Guy
