Abstract
A wavelength tunable laser device includes a gain element that provides optical gain. A laser cavity includes at least two cavities, wherein each of the at least two cavities has a different optical cavity length. At least two optical modulators are positioned in the laser cavity, wherein the at least two optical modulators are driven with waveforms so as to tune a wavelength of the wavelength tunable laser device.
