Patent number: 11387619Abstract: An optical system allows sharing of optical components and seed and pump light to achieve desired optical amplification in laser light while reducing the number of optical components and complexity of the overall optical system and achieving improved performance in lasers and reduced cost in fabrication and final lasers for large scale production of such lasers. Different optical gain sections can be used to allow for sharing of seed and pump light and sharing of optical components while providing multi-stage optical amplification.Type: GrantFiled: March 6, 2020Date of Patent: July 12, 2022Assignees: ITF TECHNOLOGIES INC., O-NET COMMUNICATIONS (SHENZHEN) LIMITEDInventors: Stéphane Caplette, Hong Xie, Nigel Holehouse, Julien Magné

Patent number: 7903697Abstract: A tunable pulsed laser includes a seed source and an optical circulator. The optical circulator includes at least a first port coupled to the seed source, a second port, and a third port. The laser also includes an amplitude modulator characterized by a first optical side and a second optical side. The first optical side is coupled to the second port of the optical circulator. The laser further includes a first optical amplifier characterized by an input end and a reflective end. The input end is optically coupled to the second side of the amplitude modulator. The laser additionally includes a tap coupler optically coupled to the amplitude modulator and characterized by a pre-determined split ratio. Moreover, the laser includes a first photo-detector optically coupled to the tap coupler and adapted to receive a portion of the seed signal transmitted through the amplitude modulator and to generate an output signal.Type: GrantFiled: January 15, 2009Date of Patent: March 8, 2011Assignee: PyroPhotonics Lasers Inc.Inventors: Richard Murison, Tullio Panarello, Benoit Reid, Reynald Boula-Picard, Stephane Caplette

Patent number: 6888624Abstract: This invention provides a method of obtaining accurate measurements of polarization dependent loss and insertion loss during the tests aiming at measuring the polarization properties of optical components. This is achieved by taking into account every polarization disturbance in the line between generation of known states of polarization and the device under test. The method involves computing within a desired range of wavelengths either the transfer matrix of each polarization perturbing element or of all polarization perturbing elements as a whole, and compensating for errors introduced by these polarization perturbing elements.Type: GrantFiled: February 8, 2002Date of Patent: May 3, 2005Assignees: ITF Technologies Optiques Inc., ITF Optical Technologies Inc.Inventors: Stéphane Caplette, Sylvain Cloutier, Charles Massicotte, Alain Villeneuve
