Patent number: 11509116Abstract: An internal laser component of an optical device comprises: a waveguide that defines a guided mode of a first optical wave characterized by a first propagation constant associated with a first effective refractive index. An optical antenna grating comprises: a waveguide that defines a guided mode of a second optical wave characterized by a second propagation constant associated with a second effective refractive index, and a grating structure configured to emit a portion of the second optical wave in a selected direction. The internal laser component and the optical antenna grating are configured to provide a relationship between the first effective refractive index and the second effective refractive index such that the selected direction is substantially insensitive to a change in a temperature of a thermal environment in which the internal laser component and the optical antenna grating are thermally coupled.Type: GrantFiled: October 18, 2019Date of Patent: November 22, 2022Assignee: Analog Photonics LLCInventors: Diedrik Vermeulen, Patrick Callahan, Michael Watts, Ehsan Hosseini, Christopher Vincent Poulton

Patent number: 11409059Abstract: Structures and methods for passively aligning a photonic die with a receiving substrate are described. Three alignment surfaces, having dimensions greater than a desired alignment accuracy, may be formed on the photonic die and used to passively and accurately align the photonic die to a receiving substrate in six degrees of freedom. Two of the three alignment surfaces on the photonic die may be formed in a single mask-and-etch process, while the third alignment surface may require no patterning or etching. Three complementary alignment surfaces on the receiving substrate may be formed in a single mask-and-etch process.Type: GrantFiled: October 26, 2020Date of Patent: August 9, 2022Assignee: Acacia Communications, Inc.Inventors: Diedrik Vermeulen, Christopher Doerr
