Stimulated Emission With Evanescent Gain in the Total Internal Reflection Geometry (JW1A.128)

Presenter: Mikhail Noginov, Norfolk State University

We demonstrated amplified spontaneous emission (ASE) enabled by evanescent gain at an interface between two adjacent dielectrics. The ASE wave is outcoupled to the high-index medium at the critical angle, enabling observation of spectacular emission rings.
