Coherent Interactions between Optical Waveguides and Lasers

Abstract: Theoretical and experimental studies of the electromagnetic coupling between parallel, passive, glass-fiber waveguides and active (Nd3+-doped laser) resonators are reported. Predicted evanescent-wave coupling strengths are verified to within a factor of two. Far-field interference patterns of these phase-locked, optical waveguides manifest a high degree of coherence and give the predicted asymmetry. Coupling of two fiber lasers is also demonstrated through common-cavity end-mirror reflectors; a high-frequency self-Q-switching action is found when the fiber ends are not rigidly mounted.
