Patent number: 10732265Abstract: An optical illuminator assembly such as an integrated module can provide an illumination source for use in applications such as optical detection. A peak output power of the module can be enhanced as compared to other approaches, such as by one or more of controlling parasitic effects along an electrical pathway used to drive an optical emitter circuit included as a portion of the module, or by providing thermal management including establishing thermal conduction pathways through opposite surfaces of an optical emitter circuit such as an integrated circuit die comprising a solid-state optical emitter. Control schemes can be used that power various cells or functional blocks of the optical emitter independently. Thermal regulation can be provided by an active heat transfer element such as a thermoelectric cooler (TEC). An optical illuminator assembly can be optically coupled to a beam-steering device or other elements, such as using a self-aligning mechanical configuration.Type: GrantFiled: April 11, 2019Date of Patent: August 4, 2020Assignee: Analog Devices, Inc.Inventors: Krishnan Ramaswamy Parameswaran, Xu Tang, Ying-Ju Wang, Weidong Wang, David Bolognia, Scott Robert Davis, Christophe Antoine, Brian Hall
