  • Patent number: 10811839
    Abstract: The present disclosure is generally directed to a TO can laser package that includes an off-center focus lens integrated into a lens cap to compensate displacement of an associated laser diode. The TO can laser package includes a TO header with a mounting structure for directly electrically coupling an associated laser diode to electrical leads/pins without the use of an intermediate interconnect. The mounting structure displaces the laser diode such that an emission surface, and more particularly, an origin thereof, is displaced/offset relative to a center of the TO header. The integrated lens cap includes a focus lens with an optical center that is offset from a center of the TO header at a distance that is substantially equal to the displacement of the laser diode. Thus, the displacement of the laser diode is compensated for by the off-center focus lens to minimize or otherwise reduce optical misalignment.

  • Patent number: 10791923
    Abstract: An optical probe includes first and second light guiding components, and a ball lens arranged along an optical axis and enclosed in a sheath having asymmetric optical power. The probe transmits at least two light beams including first and second beams each having a different wavelength. The ball lens has a curved surface and an angled surface arranged such that light is reflected off from the angled surface and focused by the curved surface at a working distance with a beam waist profile having lateral and longitudinal directions. Beam waist locations of the first and second beams are different from each other, and the beam waist profiles of the first and second beams in the lateral direction differs less than the beam waist profiles in the longitudinal direction. This ball lens design compensates for the sheath asymmetric optical power and provides balanced astigmatism and substantially achromatic performance.

    Abstract: In an optical system that includes a coherent light source and an optical waveguide, a pulse width used by the optical waveguide to project image frames on a display is changed on a frame-by-frame basis. By changing the pulse width for each image frame, the locations and characteristics of visible interference patterns on the display are changed for each successive image frame. Changing the interference patterns for each image frame may result in the interference patterns being less detectable to a viewer. The change in pulse width for each image frame may be fixed or dynamic, and may be made in response to interference patterns being detected on the display.

  • Patent number: 10603109
    Abstract: This invention relates to an advance in the delivery of laser beams to internal surgical sites using optical fibers with a novel distal tip design made using a fusion assembly procedure suitable for directing laser beams out of the side of an optical fiber. This side-fire fiber delivery tip assembly is fabricated by fusing a transparent tube onto the distal ends of a laser beam delivery fiber and an associated coaxial stub fiber that have beveled and parallel end faces that meet inside of the transparent tube. The result is a rugged fiber delivery tip assembly that is almost entirely solid, except for a very narrow gap between the beveled end surfaces of the two fibers. A loose fitting transparent capsule is placed over this fiber tip to contain a transparent perfluorocarbon lubricating oil or a perfluorocarbon heat-transfer agent that serves as a cooling agent for the fiber tip assembly.

  • Patent number: 10571636
    Abstract: A light-transmitting substrate has at least a first and a second major external surface. An electronic display source emanates light waves. A coupling-in optical arrangement couples light waves from the electronic display source into the light-transmitting substrate to effect total internal reflection of the coupled-in light waves between the major external surfaces of the light-transmitting substrate. An optical element is deployed in an optical path for light waves to traverse from the electronic display source into the light-transmitting substrate. The optical element defines a field curvature that causes light rays of the traversing light waves to diverge or converge. A lens is deployed in the optical path and reduces the field curvature. The electronic display source has a curvature that is matched to the reduced field curvature to counteract the divergence or convergence of the light rays caused by the reduced field curvature.

The output coupler is disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide component. The output coupler is partially transmissive to ambient light incident through the world facing surface. The display light is guided between the input coupler and the output coupler entirely by total internal reflection.

  • Patent number: 10156687
    Abstract: This optical receptacle has a first optical surface, a reflection surface, a second optical surface, a light separation part, and a third optical surface. On the first optical surface, light from a photoelectric conversion element is incident. The reflection surface reflects the light incident on the first optical surface. The second optical surface allows the light reflected by the reflection surface to be emitted toward an end surface of an optical transmission body. The light separation part separates the light reflected by the reflection surface, into monitor light and signal light. The third optical surface allows the monitor light to be emitted toward a detection element. The light separation part includes divided reflection surfaces and divided transmission surfaces. At least one of the divided transmission surfaces includes one or more widened portions each having a width larger than those of the other divided transmission surfaces.

In embodiments, the polymer is photo-definable, such as a negative resist, and may be patterned through direct laser writing. In embodiments, the optical component is a thin film affixed to the substrate through micro-transfer printing. In other embodiments, the optical component is a semiconductor chip affixed to the substrate by flip-chip bonding.

  • Patent number: 9791641
    Abstract: Inverted 45° semiconductor mirrors as vertical optical couplers for PIC chips, particularly optical receivers and transmitters. An inverted 45° semiconductor mirror functions to couple light between a plane in the PIC chip defined by thin film layers and a direction normal to a top surface of the PIC chip where it may be generated or collected by an off-chip component, such as a wire terminal. In an exemplary embodiment, a (110) plane of a cubic crystalline semiconductor may provide a 45° facet inverted relative to a (100) surface of the semiconductor from which light is to be emitted. In further embodiments, a (110) plane may be exposed by undercutting a device layer of a semiconductor on insulator (SOI) substrate. Alternatively, a pre-etched substrate surface may be bonded to a handling wafer, thinned, and then utilized for PIC waveguide formation.
