Publication number: 20240039244Abstract: Implementations disclosed herein provide semiconductor resonator based optical multiplexers that achieve enhanced bandwidth range of light emitted therefrom. The present disclosure integrates silicon devices into resonator structures, such as micro-ring resonators, that couples a side mode with a lasing mode and resonantly amplifies coupled light to output light having an enhanced bandwidth with respect to the lasing mode. In some examples, the optical multiplexers disclosed herein include a bus waveguide; a first resonator structure optically coupled to the bus waveguide and comprising an optical amplification mechanism that generates light and a single mode filter to force the generated light into single-mode operation; and a second resonator structure optically coupled to the first resonator structure and comprising a phase-tuning mechanism. The phase-tuning mechanism can be controlled to detune phase of light in the second resonator relative to the light in the first resonator.Type: ApplicationFiled: July 27, 2022Publication date: February 1, 2024Inventors: STANLEY CHEUNG, DI LIANG, RAYMOND G. BEAUSOLEIL, MICHAEL RENNE TY TAN, WAYNE VICTOR SORIN

Publication number: 20230283396Abstract: Systems and methods are provided for achieving graceful bandwidth scaling (i.e. higher data transmission rates) for Coarse Wavelength Division Multiplexing (CWDM) and CWDM-4 technologies. Examples utilize a waveband architecture built around the CWDM wavelengths. This waveband architecture adds additional wavelength transmission channels (which may equate to faster data transmission rates) while maintaining backwards compatibility with existing CWDM/CWDM-4 technologies. Examples may include waveband devices (e.g. waveband light sources, waveband transmitters, waveband receivers, waveband transceivers, etc.) designed to operate with one or more CWDM wavebands while maintaining backwards compatibility with existing CWDM-4 technologies.Type: ApplicationFiled: March 4, 2022Publication date: September 7, 2023Inventors: SAGI VARGHESE MATHAI, Michael Renne ty TAN, Wayne Victor SORIN

Patent number: 11588298Abstract: Coupled-cavity vertical cavity surface emitting lasers (VCSELs) are provided by the present disclosure. The coupled-cavity VCSEL can comprise a VCSEL having a first mirror, a gain medium disposed above the first mirror, and a second mirror disposed above the gain medium, wherein a first cavity is formed by the first mirror and the second mirror. A second cavity is optically coupled to the VCSEL and configured to reflect light emitted from the VCSEL back into the first cavity of the VCSEL.

Patent number: 11415763Abstract: Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. Pluggable optical transceiver modules implement a rigid-plane jumper that provides an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in a manner that does not require the fiber jumper, while ensuring reduced optical loss. In some embodiments one or more rigid waveguide plates act as an opto-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, the rigid waveguide plates are coupled to a faceplate connector, and a CWDM block that is in turn optically coupled to the optical socket. In some embodiments, the CWDM block is directly attached to the rigid waveguide plates. In some embodiments, the CWDM block is indirectly attached to the rigid waveguide plates using a half periscope.Type: GrantFiled: August 7, 2020Date of Patent: August 16, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Kevin B.
