P. Besnard et al., MICROWAVE-SPECTRA IN EXTERNAL-CAVITY SEMICONDUCTOR-LASERS - THEORETICAL MODELING OF MULTIPASS RESONANCES, IEEE journal of quantum electronics, 30(8), 1994, pp. 1713-1722
We show theoretically that the behavior of an external-cavity semicond
uctor laser depends on the microscopic intensity distribution of the f
eedback light. Adapted rate equations are developed based on the trave
ling-wave model. This model successfully predicts the double-peaked st
ructure of the external-cavity resonance (centered around c/2L) and mu
ltiple-pass resonances when the system is misaligned.
