Micro-cavity sustaining whispering gallery mode (WGM) has been widely used in physical parameter sensing and biosensing applications. We explored three type micro-cavity enhancement methods to realize highly sensitive optical fiber sensors. Firstly, optofluidic-enhanced micro-cavity optical fiber sensors are discussed. Secondly, optomechanical oscillation micro-cavity optical fiber sensor is introduced using a hollow silica microbubble cavity. Finally, fiber laser enhancement mechanism is proposed to avoid the difficulty in direct fabrication of active micro-cavity.
