==Systems and Methods for Wavelength Locking in Optical Sensing Systems - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18519035 titled 'Systems and Methods for Wavelength Locking in Optical Sensing Systems

==Simplified Explanation==

The integrated photonics device described in the abstract includes a frequency stabilization subsystem for monitoring and adjusting the wavelength of light emitted by light sources. The device utilizes selectors to combine, select, and filter light along various paths, with output signals generated by detectors to stabilize the wavelength.

* The device includes a frequency stabilization subsystem for monitoring and adjusting the wavelength of light emitted by light sources.
* Selectors such as arrayed waveguide gratings, ring resonators, and filters are used to combine, select, and filter light along different paths.
* Output signals from detectors are used to generate signals for adjusting the wavelength of the light sources.
* A controller monitors and adjusts the wavelength to lock it to a target wavelength or range.

== Potential Applications ==
This technology can be applied in:
* Telecommunications for wavelength division multiplexing systems
* Optical sensing and metrology for precise wavelength control
* Quantum computing for stable and accurate light sources

== Problems Solved ==
* Instability in wavelength of light emitted by sources
* Lack of precise control over light wavelengths
* Difficulty in maintaining consistent performance in photonics devices

== Benefits ==
* Improved accuracy and stability in wavelength control
* Enhanced performance in optical communication systems
* Increased efficiency in quantum computing applications

== Potential Commercial Applications ==
Optical Frequency Stabilization for Enhanced Photonics Devices


==Original Abstract Submitted==

Disclosed herein is an integrated photonics device including a frequency stabilization subsystem for monitoring and/or adjusting the wavelength of light emitted by one or more light sources. The device can include one or more selectors that can combine, select, and/or filter light along one or more light paths, which can include light emitted by a plurality of light sources. Example selectors may include, but are not limited to, an arrayed waveguide grating (AWG), a ring resonator, a plurality of distributed Bragg reflectors (DBRs), a plurality of filters, and the like. Output light paths from the selector(s) can be input into one or more detector(s). The detector(s) can receive the light along the light paths and can generate one or more signals as output signal(s) from the frequency stabilization subsystem. A controller can monitor the wavelength and can adjust or generate control signal(s) for the one or more light sources to lock the monitored wavelength to a target wavelength (or within a targeted range of wavelengths).
