1. An integrated optoelectronic system, comprising:

  • input and output optical waveguides;

    a tunable optical device coupled to the input and output optical waveguides, the tunable optical device having one or more tuning elements for varying one or more characteristics of the tunable optical device;

    an optical source coupled to the input waveguide for providing a calibration signal to the tunable optical device;

    an optical detector coupled to the output optical waveguide for measuring an intensity of the optical signal output by the tunable optical device in response to receiving the calibration signal; and

    an electronic controller coupled to the optical detector and the one or more tuning elements of the tunable optical device and configured to perform a calibration of the tunable optical device by varying a parameter of each of the one or more tuning elements and to receive intensity measurements of the optical signal output by the device as a function of the varied parameter;

    wherein the optical waveguides, the optical device, the optical source, the optical detector and the electronic controller are formed on a single substrate.
