Weak-coupling microcavities [PDF]

, 2017
In this chapter we address the optical properties of microcavities in the weak-coupling regime and review the emission of light from microcavities in the linear regime. We present a derivation of the Purcell effect and stimulated emission of radiation by

Tunable cavity coupling of the zero phonon line of a nitrogen-vacancy defect in diamond

New Journal of Physics, 2015
We demonstrate the tunable enhancement of the zero phonon line of a single nitrogen-vacancy colour centre in diamond at cryogenic temperature. An open cavity fabricated using focused ion beam milling provides mode volumes as small as 1.24 μ m ^3 (4.7 ...
