摘要:
An apparatus and method for automated calibration of an optical device are disclosed. The apparatus is an integrated optoelectronic system that includes input and output optical waveguides, a tunable optical device, an optical source, an optical detector, and an electronic controller formed on a single substrate. The tunable optical device has one or more tuning elements for varying one or more characteristics of the device. The optical source is coupled to the input waveguide for providing a calibration signal to the device. The optical detector is coupled to the output optical waveguide for measuring an intensity of the optical signal output by the device in response to receiving the calibration signal. The electronic controller is configured to perform a calibration of the device by varying a parameter of each tuning element and to receive intensity measurements of the optical signal output by the device as a function of the varied parameter.
