Patent number: 11405105Abstract: High power, high speed VCSEL arrays are employed in unique configurations of arrays and sub-arrays. Placement of a VCSEL array behind a lens allows spatial separation and directivity. Diffusion may be employed to increase alignment tolerance. Intensity modulation may be performed by operating groups of VCSEL emitters at maximum bias. Optical communications networks with high bandwidth may employ angular, spatial, and/or wavelength multiplexing. A variety of network topologies and bandwidths suitable for the data center may be implemented. Eye safe networks may employ VCSEL emitters may be paired with optical elements to reduce optical power density to eye safe levels.Type: GrantFiled: February 24, 2021Date of Patent: August 2, 2022Assignee: Lumentum Operations LLCInventors: John R.

Publication number: 20220082733Abstract: Embodiments comprise a system created through fabricating a lens array through which lasers are emitted. The lens array may be fabricated in the semiconductor substrate used for fabricating the lasers or may be a separate substrate of other transparent material that would be aligned to the lasers. In some embodiments, more lenses may be produced than will eventually be used by the lasers. The inner portion of the substrate may be formed with the lenses that will be used for emitting lasers, and the outer portion of the substrate may be formed with lenses that will not be used for emitting lasers—rather, through etching these additional lenses, the inner lenses may be created with a higher quality.Type: ApplicationFiled: November 22, 2021Publication date: March 17, 2022Inventors: Richard F. CARSON, John R. JOSEPH, Mial E. WARREN, Thomas A. WILCOX

Patent number: 10038304Abstract: A VCSEL array device formed of an array of raised VCSELs on an electrical contact and raised inactive regions connected to the electrical contact. The VCSELs can be physically and/or electrically organized to improve power or speed, or in phase and in parallel. The VCSELs and inactive regions are positioned between the electrical contact and an electrical waveguide. The VCSELs may be separated into subarrays and each VCSEL may be covered with an integrated or bonded microlens for directing beams of light without external lenses. The VCSELs may also be electrically selected to form two or more groups, with beams of light from each group have unique divergences, unique power or unique optical power, and each beam of light in a group forming a spot at a point on a line, on the same optical axis, or as part of a pattern.Type: GrantFiled: July 29, 2015Date of Patent: July 31, 2018Assignee: TRILUMINA CORP.Inventor: John R.

Patent number: 9065239Abstract: A top emitting VCSEL array may be coupled to a separate heat spreading superstrate that may be positioned above the apertures of the array and that may be able to transmit the emitted beams through the heat spreading superstrate. The VCSEL devices in the array may be controlled by an electrical connection to a pattern of conductive elements positioned in close contact with, but electrically isolated from, the heat spreading superstrate. The conductive elements may electrically control one or more of the VCSEL devices to enable sectional control of the light output. The elements may also be arraigned in a ground-signal-ground or coplanar waveguide configuration to improve the frequency response of the array.Type: GrantFiled: April 17, 2013Date of Patent: June 23, 2015Assignee: TriLumina Corp.Inventors: John R.
