Publication number: 20210255405Abstract: Conventional systems use a polarization-maintaining fiber (PMF) in order to maintain the light in the same polarization between a laser light source and an optical waveguide on a photonic integrated circuit (PIC). A polarization controller may be provided at an input port of the PIC configured for the manipulation of one or both of the TE0 and TM0 polarized light modes. The polarization controller may include a polarization beam splitter/rotator (PBSR), including a plurality of phase tuners and a plurality of couplers which are coupled together by waveguides, all of which are integrated in a device layer on the PIC.Type: ApplicationFiled: February 14, 2020Publication date: August 19, 2021Inventors: Richard Younce, Matthew Streshinsky, Michael J.

Patent number: 10901153Abstract: In Mach-Zehnder interferometer (MZI) based modulators (MZM) input laser light comes in from one side, gets split into two MZI arms, then recombined at an opposite side. Each MZI arm may be phase or intensity modulated depending on the set phase offset, whereby coherent or intensity modulation may be performed which can later be de-coded by a receiver. Ring resonator type modulators (RRM) are compact; however, their phase response is nonlinear, normally limiting their application in coherent phase modulation. However, a combined MZI RRM overcomes the shortcomings of the prior art by providing a novel structure and driving scheme for use with semiconductor photonics that takes advantage of the compactness of ring modulators and the linearity of MZI by setting the ring resonators to resonate at the input laser light wavelength.Type: GrantFiled: December 24, 2018Date of Patent: January 26, 2021Assignee: Elenion Technologies, LLCInventors: Yangjin Ma, Alexandre Horth, Matthew Streshinsky, Ruizi Shi, Rafeed Sukkar, Richard Younce, Michael J.

Publication number: 20200112374Abstract: A high data rate, high sensitivity, low power optical link using low-bandwidth components and low-bandwidth E/O drivers and receivers and method of building same. The method is based on the idea of making the optical part of the link look like a bandwidth limited lossy electrical channel, so that the powerful equalization methods used in the wireline electrical links can be applied to recover the transmitted data in a situation with low bandwidth and/or high loss and strong inter-symbol interference. Linear and non-linear optical channel components, E/O drivers and receivers can benefit from the apparatus and the methods of the invention.Type: ApplicationFiled: November 28, 2019Publication date: April 9, 2020Inventors: Alexander Rylyakov, Richard Younce, Ran Ding, Peter D.

Publication number: 20060217971Abstract: Voice Quality Enhancement is performed directly in a coded domain. At least one parameter of a first encoded signal is modified, which results in a corresponding at least one modified parameter. The at least one parameter of the first encoded signal is replaced with the at least one modified parameter, which results in a second encoded signal which, in a decoded state, approximates a target signal that is a function of at least the first encoded signal in at least a partially decoded state. Thus, the signal does not have to go through intermediate decoder/re-encoder(s), which can degrade overall speech quality. Computational resources required for a complete re-encoding are not needed. Overall delay of the system is minimized. The CD-VQE system can be used in any network in which signals are communicated in a coded domain, such as a Third Generation (3G) wireless network.Type: ApplicationFiled: June 22, 2005Publication date: September 28, 2006Applicant: Tellabs Operations, Inc.Inventors: Rafid Sukkar, Richard Younce, Peng Zhang
