Claim:
1. A method of controlling operation of an electro-optic modulator, comprising: receiving a first intensity of light at an input to the electro-optic modulator; receiving a second intensity of light at an output of the electro-optic modulator, wherein the electro-optic modulator includes two coupled optical waveguides for producing the output light from the input light; and heating one of the two coupled optical waveguides to control a biasing of a modulator transfer function of the electro-optic modulator that relates an intensity of light at the output of the electro-optic modulator to a wavelength to control the operation of the electro-optic modulator, wherein an amount of heating is based on a difference between the received first intensity and the received second intensity.
