Abstract

Tubular Microcavities In article number 2000163, Yongfeng Mei and co-workers realize a wide-range mode selection in a tubular mesh-structured microcavity by combining the whispering gallery mode-type resonance and distributed feedback effect. Switching between single-mode and multi-mode resonance is achieved at different axial positions in an individual microcavity. The modified microcavity should have a promising future in micro-/nano-optical devices.
