Spontaneous emission into a planar optical waveguide mode by an atom outside the waveguide

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/117151An electronically excited atom or molecule located outside but near a planar optical waveguide can decay by spontaneous emission of a photon into a guided mode of the waveguide. We outline a QED theory for calculating the probability for this process and describe general physical insights from that theory. A couple of representative examples are discussed in detail.13 pages 3 figuresQuantum PhysicsSpontaneous emission into a planar optical waveguide mode by an atom outside the waveguidetext
