We propose a novel chirp compensation scheme for directly modulated three-section distributed Bragg reflector (3s-DBR) lasers in applications of the time- and wavelength-division multiplexed passive optical network systems. The frequency chirp of 3s-DBR lasers induced by direct modulation is investigated through extensive numerical simulations based on the time-domain travel-wave model. To overcome...
In this paper, we proposed a widely tunable distributed Bragg reflector (DBR) laser based on digital concatenated grating with multiple phase shifts (MPS-DCG). The MPS-DCG can provide a comblike reflectivity spectrum with flat envelop covering over 100-nm wavelength range. Static characteristics of the MPS-DCG DBR laser, including the wavelength tuning range, output power, side-mode suppression ratio...
