  • Patent number: 11137558
    Abstract: An optical receptacle includes an optical receptacle main body and a filter. The optical receptacle main body includes a first optical surface, a second optical surface, a third optical surface, and a reflecting surface. The filter includes a first filter that reflects light of a first wavelength and allows light of a second wavelength to pass therethrough, and a second filter that reflects the light of the second wavelength and allows the light of the first wavelength to pass therethrough. The filter is disposed on the optical receptacle main body such that the first filter or the second filter makes intimate contact with the reflecting surface. A second central axis of the second optical surface do not coincide with a light axis of a light-receiving element. A third central axis of the third optical surface do not coincide with a light axis of a light-emitting element.

  • Patent number: 11099297
    Abstract: An imaging spectro-polarimetry system includes a polarizer, a tunable laser, a number of optical nodes and an image processing circuit. The polarizer produces polarized light using light received from an object. The tunable laser generates optical local oscillator (LO) signals. Each optical node receives the polarized light and an optical LO signal, performs a heterodyne mixing and generates a digital signal. The image processing circuit receives digital signals from the optical nodes and generates a magnetogram of the object. The polarizer, the tunable laser, the plurality of optical nodes and the image processing circuit are implemented on a photonic integrated circuit (PIC), and the polarized light includes right and left circularly polarized light.

  • Patent number: 11092761
    Abstract: A system and method of forming an optical connection. A fiber optic cable includes a first optical fiber and a second optical fiber. The second optical fiber includes a reflective device. An optical device receives the first optical fiber and the second optical fiber. A first signal is observed to verify an optical connection between the first optical fiber and the optical device to verity the optical connection. The fiber optic cable is extended into the optical device to form a secure mating between the first optical fiber and the optical device, thereby changing a state of the reflective device. The secure mating between the first optical fiber and the optical device is determined from the state of the second signal in the second optical fiber.

  • Patent number: 11067754
    Abstract: Optical interconnects can offer higher bandwidth, lower power, lower cost, and higher latency than electrical interconnects alone. The optical interconnect system enables both optical and electrical interconnection, leverages existing fabrication processes to facilitate package-level integration, and delivers high alignment tolerance and low coupling losses. The optical interconnect system provides connections between a photonics integrated chip (PIC) and a chip carrier and between the chip carrier and external circuitry. The system provides a single flip chip interconnection between external circuitry and a chip carrier using a ball grid array (BGA) infrastructure. The system uses graded index (GRIN) lenses and cross-taper waveguide couplers to optically couple components, delivers coupling losses of less than 0.5 dB with an alignment tolerance of ±1 ?m, and accommodates a 2.5× higher bandwidth density.

  • Patent number: 11052436
    Abstract: A laser cleaning apparatus and a laser cleaning method are furnished, for switching the wavelengths of laser beams furnished by a single laser module using a wavelength switching module and cleaning a test piece using the laser beams having wavelengths and energy suitable for manufacturing needs. The laser cleaning method includes: creating a laser beam; switching the wavelength output by the laser based on process requirements; propagating the laser beam via an optical path propagating module for laser cleaning the test piece; and removing debris. A transfer platform allows movements of the laser beams with respect to the test piece to achieve cleaning of the entire test piece. A control module controls the wavelength switching unit, the laser beam regulating module, and the transfer platform. Total laser cleaning with improved laser cleaning quality is achieved by using these laser beams with the appropriate wavelengths and energy.
