Lingfang Wang’s paper “Theoretical Modelling of Single-Mode Lasing in Microcavity Lasers via Optical Interference Injection” was published in Optics Express ( Vol. 28, Issue 11, pp. 16486-16496 (2020) ).
We develop a rate equation model which considers the spatially modulated gain and spontaneous emission, which are inherently governed by the ripple of the vacuum electromagnetic field in a Fabry-Pérot (FP) microcavity. By manipulating the interplay between the spatial oscillation of the vacuum field and external optical injection via dual-beam laser interference, single longitudinal mode operation is observed in a FP-type microcavity with a side mode suppression ratio exceeding 40 dB.
Congratulations!
