Title:
FAST TEMPERATURE TUNING FOR OPTICAL RECEIVERS
Document Type and Number:
WIPO Patent Application WO/2020/170062
Kind Code:
A1
Abstract:
A new and improved tunable optical receiver based on thermal optics and controllers for technologies that require fast wavelength channel tuning. The device entails a thermal control system in which a wavelength tunable filter, a sensor and at least two thermal actuators enables fast tuning, which are controlled by advanced algorithms. The key compositions of both parts are outlined and their main requirements are discussed
