Purcell effect in PT-symmetric waveguides
Alina Karabchevsky, Andrey Novitsky, Fyodor Morozko
This chapter overviews the principles of the spontaneous emission rate increase, that is the Purcell effect, in relation to the photonic parity-time (PT) symmetry. Being focused on…

Modal Purcell factor in -symmetric waveguides
Fyodor Morozko, Andrey Novitsky, Alina Karabchevsky
We study the spontaneous emission rate of a dipole emitter in -symmetric environment of two coupled waveguides using the reciprocity approach generalized to non-ortho…
