==MACH-ZEHNDER INTERFEROMETER DEVICE FOR WAVELENGTH LOCKING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240094592 titled 'MACH-ZEHNDER INTERFEROMETER DEVICE FOR WAVELENGTH LOCKING

==Simplified Explanation==

The integrated photonics device described in the abstract includes an on-chip wavelength stability monitor that utilizes interferometric components to monitor the wavelength emitted by a photonic component. The monitor can select among the output signals from the interferometric components based on the slope of the signal, and may correspond to a working zone at or around a specific wavelength or wavelength range. The interferometric components can be configured with different phase differences to have working zones at different wavelengths, and the slopes of the output signals may be weighted based on their steepness to lock the measured wavelength to a target wavelength.

* Integrated photonics device with on-chip wavelength stability monitor

==Original Abstract Submitted==

disclosed herein is an integrated photonics device including an on-chip wavelength stability monitor. the wavelength stability monitor may include one or more interferometric components, such as mach-zehnder interferometers and can be configured to select among the output signals from the interferometric components for monitoring the wavelength emitted by a corresponding photonic component, such as a light source. the selection may be based on a slope of the output signal and in some examples may correspond to a working zone at or around a wavelength or wavelength range. in some examples, the interferometric components can be configured with different phase differences such that the corresponding working zones have different wavelengths. in some examples, the slopes of the output signals may be weighted based on the steepness of the slope and all of the output signals may include information for wavelength locking the measured wavelength to the target wavelength.
