WebAug 7, 2009 · In contrast to most evanescent field sensors, such as fiber sensors [5,6], optical waveguides [7,8], and surface plasmon resonance [9,10], which apply freely traveling waves, WGM are optical cavity mode excitations obeying a closed resonator condition, which renders them sensitive to the microcavity’s geometry [11,12]. Because of this ... WebAn optical cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric oscillators and some interferometers.
