Patent ID: 7782913

Claim:
A method of controlling an optical package comprising a semiconductor laser, a spectral filter, and a wavelength conversion device, wherein: the spectral filter and the wavelength conversion device collectively define a wavelength transfer function comprising a transmission bandwidth component attributable to the spectral filter and a conversion bandwidth component attributable to the wavelength conversion device; the transmission bandwidth component attributable to the spectral filter is less than one free spectral range of the semiconductor laser; the semiconductor laser is configured to generate a native laser output comprising a native wavelength spectrum that can be tuned over a range equal to or larger than the transmission bandwidth component attributable to the spectral filter and the conversion bandwidth component attributable to the wavelength conversion device; and the method comprises directing the native laser output through the spectral filter and the wavelength conversion device and tuning the semiconductor laser to modulate the intensity of a wavelength-converted laser output of the optical package by shifting the native wavelength spectrum by less than one free spectral range of the semiconductor laser.
