Abstract
Systems, and related methods, relating generally to electro-absorption modulation are described. In a system therefor, there is a waveguide. A photodetector is configured with respect to the waveguide for detecting luminous intensity of an optical signal. An electro-absorption modulator is configured with respect to the waveguide for electro-absorption modulation of the optical signal. An integrated heating element is located alongside and spaced apart from both the photodetector and the electro-absorption modulator. the integrated heating element is configured for controllably heating the photodetector and the electro-absorption modulator.
