Patent number: 11742630Abstract: A structured light system may include a semiconductor laser to emit light and a diffractive optical element to diffract the light such that one or more diffracted orders of the light, associated with forming a structured light pattern, are transmitted by the diffractive optical element. The diffractive optical element may be arranged such that the light is to be incident on the diffractive optical element at a substantially non-normal angle of incidence. The substantially non-normal angle of incidence may be designed to cause the diffractive optical element to transmit a zero-order beam of the light outside of a field of view associated with the diffractive optical element.Type: GrantFiled: September 3, 2021Date of Patent: August 29, 2023Assignee: Lumentum Operations LLCInventors: Vincent V.

Patent number: 9065237Abstract: Multi-mode diode emitters are stacked in a staircase formation to provide a spatially-multiplexed output. Improved coupling efficiency is achieved by providing tilted collimated output beams that determine an effective step height of the stepped structure. Since the effective step height is dependent on the tilt angle, a variable number of emitters can be used inside packages having a same physical step height, while still attaining high coupling efficiency.Type: GrantFiled: December 7, 2011Date of Patent: June 23, 2015Assignee: JDS Uniphase CorporationInventors: James Yonghong Guo, Jay A.

Patent number: 9036678Abstract: A fiber coupled semiconductor device and a method of manufacturing of such a device are disclosed. The method provides an improved stability of optical coupling during assembly of the device, whereby a higher optical power levels and higher overall efficiency of the fiber coupled device can be achieved. The improvement is achieved by attaching the optical fiber to a vertical mounting surface of a fiber mount. The platform holding the semiconductor chip and the optical fiber can be mounted onto a spacer mounted on a base. The spacer has an area smaller than the area of the platform, for mechanical decoupling of thermally induced deformation of the base from a deformation of the platform of the semiconductor device. Optionally, attaching the fiber mount to a submount of the semiconductor chip further improves thermal stability of the packaged device.Type: GrantFiled: July 27, 2010Date of Patent: May 19, 2015Assignee: JDS Uniphase CorporationInventors: Reddy Raju, Richard L.

Patent number: 9008139Abstract: A high field of view, low height package and wafer-level packaging process are provided. The top surface of a first wafer has recesses defined by sidewalls, with a reflector, and a floor. The reflector is incident a horizontal light path form an edge-emitting diode on the floor, directing the light path vertically. A second optically diffusing wafer receives the vertically directed light. A vertical ring to surround each recess is wafer-level fabricated on one of the wafers. The vertical ring may have a high aspect ratio to increase light diffusion. The second wafer is connected above the first such that each vertical ring encloses its corresponding recess and such that the light vertically exits the optically diffusing media after spanning the height of the vertical ring. Diode electrical connections are provided for externally controlling the diode. Individual packages are separated by double-dicing the connected wafers between the recesses.Type: GrantFiled: June 28, 2013Date of Patent: April 14, 2015Assignee: JDS Uniphase CorporationInventors: Pezhman Monadgemi, Vincent V.
