Patent number: 11668927Abstract: Systems, devices, and methods for providing optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. The optical engines of the present disclosure may integrate a plurality of laser diodes (e.g., 3 laser diodes, 4 laser diodes) within a single, hermetically or partially hermetically sealed, encapsulated package. Wavelength stabilization for the laser diodes is achieved by controlling the temperature of the lasers to always be in a particular range of operating specifications which provides wavelength stabilization that meets particular performance criteria. The lasers themselves may be used for temperature control by selectively switching them on to maintain their temperature within a specified range. Alternatively, compact resistive heaters may be positioned proximate the laser diodes to control the temperature of the laser diodes during operation. WHUDs that employ such optical engines and laser projectors are also described.Type: GrantFiled: January 23, 2019Date of Patent: June 6, 2023Assignee: GOOGLE LLCInventors: Jörg Pierer, Rony Jose James, Stefan Mohrdiek, Douglas R.

Patent number: 10215367Abstract: There is provided an apparatus for wavelength conversion, comprising a wavelength converter, a first reflector, a second reflector, a third reflector, and a first lens. The first reflector has a curvature and is configured to reflect a plurality of input light beams onto the second reflector. The second reflector is configured to reflect the input light onto the third reflector. The first lens is disposed between the wavelength converter and the third reflector. The third reflector is configured to reflect the input light through the first lens and onto the wavelength converter, which is then excited to emit an emitted light. The first lens is configured to receive at least a portion of the emitted light, reduce its divergence, and at least partially transmit it to form an output light propagating towards the third reflector, which is configured to at least partially transmit the output light.Type: GrantFiled: November 9, 2016Date of Patent: February 26, 2019Assignee: CHRISTIE DIGITAL SYSTEMS USA, INC.Inventors: Daniel Robert Adema, Joseph Ma, Graham Hill, John Domm
