Abstract
Cascaded Mach-Zehnder Interferometer (CMZI) structures comprising electrically resistive heaters provisioned across the stages so as to enable improved filter wavelength control. In embodiments, CMZI heater power supply control is made a linear function by scaling the number of heater elements between the stages in proportion with the magnitude of the arm differential (e.g., ΔL, 2ΔL) for the corresponding stage.
