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 ...
WebOften there are optics in a system that define an optical axis, for example the center of curvature of two mirrors defines the optical axis of a Fabry-Perot cavity. The beam from the laser can be made to propagate along this axis by using a minimum of 2 mirrors. ... This can be achieved by placing a lens one focal length away from the beam ...
