Abstract: 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.

Abstract: An optical device may include emitter array to emit light. The optical device may include a collimating element to create an image of the light emitted by the emitter array. The optical device may include a diffractive optical element (DOE) to generate a pattern from the image of the light. The optical device may include a distortion correction element to reduce distortion in the pattern on a screen or to shape the pattern on the screen.

Abstract: A chip-scale package for an edge-emitting semiconductor device and a semiconductor device assembly including such a chip-scale package are provided. The chip-scale package includes an edge-emitting semiconductor device chip, a top submount disposed on a top surface of the chip, and a bottom submount disposed on a bottom surface of the chip. The top-submount area and the bottom-submount area are each greater than the chip area and less than or equal to about 1.2 times the chip area.

Abstract: A dot projector may include a vertical-cavity surface-emitting laser (VCSEL). The dot projector may include one or more collimating elements to collimate light emitted by the VCSEL. An effective focal length of the one or more collimating elements may be larger than an optics length of the dot projector. The dot projector may include an optical element including a periodic optical phase function to replicate the light after collimation by the one or more collimating elements and an aberration-correcting phase function to correct spot aberrations in a dot pattern resulting from the tiling or splitting of the light.

Abstract: In some implementations, a dot projector optic may include a collimating lens; a fisheye lens; and a dot aberration correction element disposed between the collimating lens and the fisheye lens. An input to the fisheye lens, from the dot aberration correction element, may be associated with a first field of view angle. An output from the fisheye lens may be associated with a second field of view angle that is larger than the first field of view angle.

Abstract: An emitter array, may comprise a first set of emitters that has a nominal optical output power at an operating voltage. The emitter array may comprise a second set of emitters that has substantially less than the nominal optical output power or no optical output power at the operating voltage. The first set of emitters and the second set of emitters may be interleaved with each other to form a two-dimensional regular pattern of emitters that emits a random pattern of light at the nominal optical output power at the operating voltage. The first set of emitters and the second set of emitters may be electrically connected in parallel.

Abstract: A laser diode assembly is disclosed, in which a transmissive reflector is used to redirect the laser beam upwards or to turn or rotate the laser beam. The reflector has at least one Brewster transmissive surface and at least one total internal reflection surface. Several total internal reflection surfaces rotated with respect to one another may be used in a single reflector to redirect and rotate the laser diode beam.
