A monolithic wavelength stabilized system comprises a laser monolithically formed with a waveguide splitter having at least two branches. Non-identical resonators having different wavelengths are operatively coupled to each branch of the splitter and a photodiode is communicatively coupled to receive the output from each non-identical resonator. A control unit receives the photocurrent outputs from the photodiodes, determines based on the photocurrents whether the wavelength of the laser signal is at a desired value, and transmits a feedback signal to the laser to move the laser output toward the desired wavelength. The laser, splitter, resonators, and photodiodes are monolithically formed in a single chip using asymmetric waveguides.
