ABSTRACT:
According to one embodiment of the present invention, an optical package comprises one or more semiconductor lasers coupled to a wavelength conversion device with adaptive optics. The optical package also comprises a package controller programmed to operate the semiconductor laser and the adaptive optics based on modulated feedback control signals supplied to the wavelength selective section of the semiconductor laser and the adaptive optics. The wavelength control signal supplied to the wavelength selective section of the semiconductor laser may be adjusted based on the modulated wavelength feedback control signal such that the response parameter of the wavelength conversion device is optimized. Similarly, the position control signals supplied to the adaptive optics may be adjusted based on the modulated feedback position control signals such that the response parameter of the wavelength conversion device is optimized.
