Patent number: 11843219Abstract: A fiber-based master optical power amplifier (MOPA) is configured to utilize a pump source that operates in pulse mode with the arrival time of the pump pulses coordinated with the arrival time of the input pulses. The width of the pump pulses is also controlled, thus providing a mechanism for controlling both the amount of pump energy injected into the fiber amplifier, as well as the overlap in time between the pump pulse and the seed pulse. As the pulse repetition interval (PRI) of the input seed pulse changes, the timing of the pump pulses and their width are also changed so that a “constant gain” environment is created within the amplifying medium, providing an essentially constant energy output pulse, regardless of differences in ASE generated during different PRIs.Type: GrantFiled: July 23, 2020Date of Patent: December 12, 2023Inventors: Martin R. Williams, Timothy K. Zahnley, Thomas W. McNamara, Aravanan Gurusami, Scott Dahl, Siegfried Fleischer

Patent number: 10564068Abstract: An OTDR system utilizes a laser source that is turned “on” and kept powered until its light reaches the end of the fiber span being measured (i.e., until the fiber span is fully illuminated). At any point in time after the fiber is fully illuminated, the laser source can be turned “off”. The return (reflected and backscattered) signal is directed into a photodetector of the OTDR, and is measured from the point in time when the fiber span starts to be illuminated. The measurements are made by sampling the return signal at predetermined time intervals—defined as the sampling rate. The created power samples are then subjected to post-processing in the form of a differentiation operation to create a conventional OTDR trace from the collected data.Type: GrantFiled: July 5, 2017Date of Patent: February 18, 2020Assignee: II-VI Delaware, Inc.Inventors: Aravanan Gurusami, Timothy Zahnley, Scott Dahl, Deepak Devicharan, Ian Peter McClean

Patent number: 9872994Abstract: A vented set screw is used to secure a connection between an implantable medical device and an implantable lead. The vented set screw includes one or more venting channels that allow liquid and/or gas to flow out of the implantable medical device when the implantable lead is being inserted into the implantable medical device and secured during an implantation procedure. This prevents pressure from building up at the connection, thereby ensuring proper performance of sensing and/or therapy delivery functions of the implantable medical device.Type: GrantFiled: August 11, 2016Date of Patent: January 23, 2018Assignee: Cardiac Pacemakers, Inc.Inventors: Lawrence D. Swanson, John M. Edgell, Nick A. Youker, Scott Dahl, Kevin P. Rodby

Patent number: 9494484Abstract: An arrangement for providing real-time, in-service OTDR measurements in an optical communication system utilizing distributed Raman amplification. One or more of the laser diodes used to provide the pump light necessary to create optical gain is modified to also generate short duration pulses that ride above or below the conventional pump light. These short duration pulses (which co-exist with the pump light within the optical fiber) are used in performing OTDR measurements, with a conventional processing system used to evaluate reflected pulses and create the actual OTDR measurements.Type: GrantFiled: February 25, 2015Date of Patent: November 15, 2016Assignee: II-VI INCORPORATEDInventors: Aravanan Gurusami, Timothy K.
