Title:
SYSTEMS AND METHOD OF MULTI-LASER WAVELENGTH CONTROL
Document Type and Number:
WIPO Patent Application WO/2020/069674
Kind Code:
A1
Abstract:
Methods and apparatus are provided for wavelength control of multiple independent laser sources to reduce relative wavelength drift between the different laser sources. According to some aspects, multiple laser wavelength control is provided using a multi-line source as a wavelength reference. According to other aspects, multiple laser wavelength control is provided using a single wavelength sensing device. The multiple independent laser sources could generate the constituent optical channels of a super-channel. Benefits could include reduced guard band width and increased spectral efficiency within the super-channel.
