|Abstract:||<p>New types of laser using the basic structure of FP cavity are designed and modeled, to achieve high SMSR single-mode lasing that can be immune to high level of optical feedbacks for optical network communication applications.</p> <p>The work includes design of asymmetric Bragg reflection waveguide laser that employs wavelength selective Bragg reflectors as the claddings to confine and filter desired FP longitudinal modes for amplification and lasing. Si-rich SiO<sub>2</sub> single-mode laser based on this structure is also proposed and analyzed.</p> <p>To optimize a recent design of discrete mode laser that is re-growth free and feedback-perturbation insensitive, a comprehensive implementation of the time domain transfer matrix method, including temperature and feedback effects, is carried out. The model helps to obtain a optimized DM structure that is balanced between high SMSR and low feedback sensitivity.</p>|
