This paper presents experimental investigations of the all-optical synchronization of a distributed Bragg reflector (DBR) laser self-pulsating at 40GHz on various injected bit-rate signals. Even though there is no modulation applied to this laser, it exhibits a modulation of its output emission, measured at 39.7GHz with a linewidth of 30MHz. Such performance is exploited in all-optical clock recovery...
We report the tuning characteristics of a widely tunable photonic crystal coupled-cavity laser and find good agreement with simulations based on a transfer matrix algorithm. The device consists of two photonic crystal channel waveguides that are longitudinally coupled through a photonic crystal section. The cavity modes exhibit slightly different mode spacing and allow a wavelength switching by utilizing...
