单向性发射微球腔的形变控制
eformation control in a high-Q deformed microsphere toward single-directional emission
本文实验研究了利用二氧化碳脉冲激光的能量和脉冲数目控制微球腔的形变。利用这种方法可以实现品质因子达10 7的方向性发射回音壁模式。同时,实验实现了高品质因子微球腔中方向性发射从两个方向到单向的转变。该具有方向性发射和高品质因子的回音壁模式将在未来的变型微腔中的混沌光学,腔电动力学和光机械等方面得到广泛应用。
High-Q deformed silica microsphere cavities are fabricated by short CO2 laser pulse sequence, where the deformation is well controlledby adjusting the intensity and number of pulses. Using this method,directional emission from Whispering-Gallery mode with a high qualityfactor of 10 7 in these microspheres is achieved, and a transition fromtwo-directional to single-directional emission is observed. Suchconcentrated directional emission and high-Q of WGMs show high potentialfor future studies of the chaotic ray dynamics in deformed microcavity and cavity quantum electrodynamics and optomechanics.
