Abstract
A hybrid laser structure (comprising III-V gain material and a silicon-based photonic integrated circuit) is configured to control the number of generated mode-locked wavelengths by including an optical wavelength filter within the photonic integrated circuit portion of the laser cavity. The optical wavelength filter is used to control the number of comb lines that are supported by the laser cavity, filtering out a set of non-selected mode-locked wavelengths to control the generated number. The optical filter may be passive or active, and the number of generated comb lines may be fixed or adjustable, as desired.
