Publication number: 20230393445Abstract: In a wavelength selective switch, an input port transmits an input beam, and diffraction grating disperses the input beam into optical channels. A liquid-crystal-on-silicon (LCoS) switch assembly has a phase grating profile and has addressable pixels, which are liquid crystal based. The LCoS switch assembly can selectively direct first-order diffracted beams of the optical channels for output to selected output ports. A tunable optical wedge adjacent the LCoS switch assembly can direct higher-order diffraction beams in the space between the output ports to reduce crosstalk. The wedge is a liquid crystal cell having spaced-apart resistive layers and having liquid crystal material disposed between the layers. In the wedge, the liquid crystal material can produce a phase profile in response to bias voltages applied to the resistive layers, and a beam steering angle of the phase profile can direct at least the second-order diffracted beams towards the port spacing between the ports.Type: ApplicationFiled: June 3, 2022Publication date: December 7, 2023Inventors: Helen Chen, Guomin Jiang, Tom Li, Lawrence Wang, Jim Yuan

Patent number: 11613560Abstract: The present invention relates to polypeptides which are covalently bound to molecular scaffolds such that two or more peptide loops are subtended between attachment points to the scaffold. In particular, the invention describes peptides which bind to OX40. The invention also relates to multimeric binding complexes of polypeptides which are covalently bound to molecular scaffolds such that two or more peptide loops are subtended between attachment points to the scaffold that are functional agonists of OX40. The invention also includes drug conjugates comprising said peptides and complexes, conjugated to one or more effector and/or functional groups, to pharmaceutical compositions comprising said peptide ligands, complexes and drug conjugates and to the use of said peptide ligands and drug conjugates in preventing, suppressing or treating a disease or disorder mediated by OX40.Type: GrantFiled: May 11, 2020Date of Patent: March 28, 2023Assignee: BicycleTx LimitedInventors: Tom Li Stephen, Kevin McDonnell, Nicholas Keen, Liuhong Chen, Helen Harrison, Peter U.

Patent number: 11016441Abstract: A two-step optimization process is utilized to define an optimal phase profile for a LCoS spatial light modulator. The two-step optimization process first utilizes a nonlinear constrained optimization (NCO) program to determine the specific parameters required to obtain an optimal phase profile (hologram), where the “optimal phase profile” is typically defined as that profile which achieves maximum diffraction efficiency for optical switching. Following this first step, phase scaling (and perhaps an adjustment in the number of pixels per period) is employed to slightly modify the values of the optimal phase profile to effectively suppress crosstalk peaks. If any orders still exhibit an unacceptable level of crosstalk, these orders are then subtracted from the phase profile to create the final design.Type: GrantFiled: February 18, 2019Date of Patent: May 25, 2021Assignee: II-VI Delaware, Inc.Inventors: Kun Gao, Jack R. Kelly, Helen Chen, Guomin Jiang, Xinran Wang, Lixin (Lawrence) Wang, Qingyu (Tom) Li, Haiji J. Yuan

Patent number: 10367596Abstract: A multiple wavelength selective switch has an optics assembly to receive a first input optical signal from a first ingress port and a second input optical signal from a second ingress port. A switch assembly has a single switching mechanism to direct the first input optical signal to the optics assembly as a first output optical signal and the second input optical signal to the optics assembly as a second output optical signal. The switch assembly directs the first output optical signal to a first egress port selected from the first set of egress ports and directs the second output optical signal to a second egress port selected from the second set egress ports. The first egress port and the second egress port have the same wavelength channel. The multiple wavelength selective switch supports an arbitrary number of wavelength channels that can be switched at the same time. Each switch assembly directs signals from a set of ingress ports to a set of egress ports sharing the same wavelength channel.Type: GrantFiled: May 22, 2018Date of Patent: July 30, 2019Assignee: II-VI Delaware, Inc.Inventors: Oliver Lu, Helen Chen, Gordon Jiang, Simon He, Lawrence Wang, Tom Li, Jim Yuan, Jack Kelly, Fenghua Li

Patent number: 8064867Abstract: A dual-band input transceiver block is formed to operably receive one of a 2.4 GHz radio frequency signal or a 5.0 GHz radio frequency transceiver signal in a manner that minimizes duplication of circuitry and creates a combined circuit path for RF front end input stages for much of the input stage. More specifically, the embodiments of the present invention include separate amplification and mixing stages whose outputs are combined by a stabilized load with circuitry for removing a common mode feedback signal. As such, downstream components, such as amplifiers, filters, analog-to-digital converters, and other input path circuit elements, are not duplicated and may be used regardless of whether the dual-band transceiver is operating in a first or second frequency band. Operation is, in the described embodiment, only one frequency input at a time though the invention is not limited to such operation.Type: GrantFiled: June 10, 2008Date of Patent: November 22, 2011Assignee: Broadcom CorporationInventors: Qiang (Tom) Li, Hooman Darabi
