Abstract :
The supermode of a 192-GHz sixth-harmonic colliding-pulse mode-locked semiconductor laser can be selected by continuous-wave (CW) light injection adjusted to the unlocked fundamental cavity modes. This selection scheme offers a technique for wide-range simultaneous multiwavelength allocation at each fundamental mode spacing and will be useful for providing standard light sources for wavelength-division multiplexed (WDM) systems.
