Patent number: 11894658Abstract: The present disclosure relates to an approach for monitoring the output power of a VCSEL or VCSEL array in a relatively compact, low profile package. A VCSEL device or VCSEL package of the present disclosure may generally be configured with a photodiode for monitoring output power of one or more VCSELs. In some embodiments, one or more VCSEL devices may be arranged over or on a photodetector, such that the photodetector is configured to detect light emitted through a bottom of the VCSEL. In such embodiments, the VCSEL device may have a patterned bottom metal layer and/or an etched substrate to allow light to pass below or behind the VCSEL to the photodiode. In other embodiments, a photodetector may be arranged on a submount adjacent one or more VCSELs, and may be configured to detect light reflected via a diffuser in order to monitor output power.Type: GrantFiled: November 29, 2018Date of Patent: February 6, 2024Assignee: VIXAR, INC.Inventors: Klein L. Johnson, David Sandquist, Mary Brenner

Patent number: 11641091Abstract: A segmented VCSEL array having a plurality of individually addressable segments, each segment comprising one or more VCSELs. In some cases, at least two of the plurality of individually addressable segments may be driven in combination. The plurality of individually addressable segments, in some embodiments, may be centered around the same central point. An optical element may be used in conjunction with the segmented VCSEL array, and in some cases may be aligned to the central point. The optical element may be configured such that light passing therethrough may be directed according to which of the plurality of individually addressable segments is activated. In some embodiments, the optical element is a grating or diffractive optical element. The grating or diffractive optical element could be patterned with optical segments that each correspond to at least one the plurality of individually addressable segments.Type: GrantFiled: August 17, 2020Date of Patent: May 2, 2023Assignee: Vixar, Inc.Inventors: William Hogan, Matthew Dummer, Klein Johnson, Mary Brenner
