Electrically injected DFB laser based on the Parity-Time symmetry concept

Résumé

The principle of Parity-Time symmetric optics is exploited for realization of electrically injected single frequency DFB lasers based on industry-adopted design and fabrication approaches. Experimental evidence is provided for “unidirectional” gain discrimination mechanism induced by the complex refractive index Bragg grating. This is expected to enhance lasers’ resistance to parasitic optical feedback. The experimental results showing an apparent correlation between the gratings real-to-imaginary phase shift and the laser feedback resistance are corroborating theoretical prediction.
