MACH-ZEHNDER INTERFEROMETER DEVICE FOR WAVELENGTH LOCKING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18526269 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 with interferometric components like Mach-Zehnder interferometers. The monitor selects output signals based on slope to monitor the wavelength emitted by a photonic component, such as a light source. The interferometric components can have different phase differences to cover various working zones with different wavelengths, and the output signals can be weighted based on slope steepness for wavelength locking.

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.
