Patent number: 10151865Abstract: Approaches to Compact External Grating PBS/PBC Coupling are described according to embodiments of the present invention. In one embodiment, a YVO4 crystal is used to split a beam or combine multiple beams into a single beam. A lens is used to convert a mode of the light to match a mode of a grating port. A glass wedge is designed to bend the light from horizontal to a nearly vertical orientation to match an exit angle of a grating port. When a source or a receiver utilizes an optical fiber, a fiber holder may be used to bond the fiber to the source or receiver. The PBS/PBC described has much less insertion loss compared to existing 2D grating coupler techniques, and has a wider spectral bandwidth due to flexibility in mode matching compared to existing 2D grating couplers.Type: GrantFiled: January 7, 2015Date of Patent: December 11, 2018Assignee: FutureWei Technologies, Inc.Inventors: Rongsheng Miao, Yusheng Bai

Patent number: 10148721Abstract: The disclosure relates to technology for network coding a video stream in an information centric network. A network node breaks a media segment (e.g., a video segment) into chunks. The chunks for one media segment are then encoded into network encoded chunks, each of which may be a linear combination of the chunks for that media segment. Thus, a number of network encoded chunks for a media segment are generated. These network encoded chunks may be provided to a client in response to a request for content in an information centric network (ICN). When the client receives enough network encoded chunks, the client decodes them to produce the original chunks for that media segment. The client may perform bit-rate adaptation based on the time it takes to receive a media segment. The client may view the communication interfaces as a logical communication link upon which to perform rate adaptation.Type: GrantFiled: January 25, 2017Date of Patent: December 4, 2018Assignee: Futurewei Technologies, Inc.Inventors: Cedric Westphal, Abinesh Ramakrishnan
