Resonant optical cavity used as a nonradiating source for optical near-field microscopy.
Nonradiating sources are emitting devices whose geometry prohibits electromagnetic emission. First, we show that a ring cavity can be substituted for the usual prism in scanning tunneling optical microscopy. Second, we find that near-field detection is an ideal way to explore the behavior of such nonradiating sources.
