Exceptional point singularities in multi-section DFB lasers

Exceptional point singularities in multi-section DFB lasers

A laser exhibits both controllable gain and loss and, under proper design conditions, is an ideal non-Hermitian system allowing the direct observation and engineering of spectral singularities such as exceptional points (EPs). A dual section distributed feedback (DFB) quantum cascade laser (QCL) is...
