  • Fast temperature tuning for optical receivers
    Patent number: 12001008
    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.
