Filed:

Jun 25, 2020

Appl. No.:

16/912308

Inventors:

- Houston TX, US
PAUL KESSLER ROSENBERG - PALO ALTO CA, US
STANLEY CHEUNG - PALO ALTO CA, US

International Classification:

H04Q 11/00
G02B 6/35

Abstract:

Waveguide shuffle blocks (WSBs) are provided that may incorporate waveguides routed in any pattern to effectuate many-to-many connectivity between optical cables/fibers or other WSBs connected thereto. Such WSBs may be configured in ways that allow the WSBs to be stacked and to achieve effective optical cable/fiber organization. Moreover, such WSBs may include readable tags that can provide information regarding a particular WSB configuration and/or what optical cables/fibers are connected so that network topology can be discovered and monitored. Some WSBs may be configured as wavelength shifting shuffles (WSSs) that allow a particular wavelength(s) of an optical signal(s) to be routed as desired and/or alter a first wavelength associated with a particular optical signal to a second wavelength. In other embodiments WSSs can be configured to allow for wavelength multiplexing/demultiplexing.

Sagi Varghese Mathai - Palo Alto CA, US
Stanley Cheung - Palo Alto CA, US

International Classification:

H01S 5/183
H01S 5/42

Abstract:

A VCSEL device includes a substrate and a first DBR structure disposed on the substrate. The VCSEL device further includes a cathode contact disposed on a top surface of the first DBR structure. In addition, the VCSEL device includes a VCSEL mesa that is disposed on the top surface of the first DBR structure. The VCSEL mesa includes a quantum well, a non-circularly-shaped oxide aperture region disposed above the quantum well, and a second DBR structure disposed above the non-circularly-shaped oxide aperture region. In addition, the VCSEL mesa includes a selective polarization structure disposed above the second DBR structure and an anode contact disposed above the selective polarization structure.

H04J 14/04
H04B 10/40

Abstract:

A VCSEL transmitter includes aa first VCSEL terminal disposed on a substrate and a second VCSEL terminal adjacent thereto. The transmitter also includes a first diffraction element within a first optical path of the first VCSEL terminal which receives and changes a first direction of a first light transmission having a low-order Laguerre Gaussian mode emitted from the first VCSEL terminal. The transmitter further includes a second diffraction element within a second optical path of the second VCSEL terminal which receives the second light transmission and converts the received light into a high-order Laguerre Gaussian mode. The transmitter also includes a mode combiner to direct the first light transmission into a lens which directs the light into a multi-mode optical fiber.

Abstract:

In the examples provided herein, a polarization diversity receiver system includes a loop waveguide, and a two-dimensional grating coupler formed on the loop waveguide to couple light impinging on the grating coupler having a first polarization into the loop waveguide in a first direction, and to couple light having a second polarization orthogonal to the first polarization into the loop waveguide in a second direction. The system also includes a first output waveguide positioned near the loop waveguide in a first coupling region, a first distributed perturbation having a first resonant wavelength in the first coupling region to cause coupling of light at the first resonant wavelength between the loop waveguide and the first output waveguide, and a first photodetector to detect light propagating out of a first end and a second end of the first output waveguide.
