Title: Temperature feedback for electro-optic phase shifters
Inventor: CASPERS JAN NIKLAS
IPC: G02B26/06
Filed: 2019-01-16
Abstract: Provided is a transmitter for an optical device, which includes semiconductor waveguides, wherein each of the semiconductor waveguides integrates electro-optic phase-shifters in the semiconductor waveguide operated to change a refractive index of the waveguide, and introduces a phase shift in the light propagating through the waveguide. The electro-optic phase-shifter is connected to a temperature measurement component such as a PTAT circuit, which is integrated into electronic or photonic chips having waveguides, and to a phase shift controller. The temperature measurement by the measurement component can be multiplexed with a normal operation of the phase-shifter so that a temperature measurement function does not interfere with the phase shifting function.
