Abstract

A method is presented for obtaining the exact propagation constants (resonance wavelengths and threshold gains) for distributed-feedback lasers. The method is based on computing the exact Green´s function for resonant cavities using a recursive Green´s function approach. The net threshold gains of distributed-feedback lasers are calculated and compared with the results obtained using conventional coupled-mode theory. The comparison reveals that coupled-mode theory is weakest for aperiodic structures
