Transmission Modes with Varying Incident Angle for Photonic Crystal Filter with Liquid Crystal Layer

Evanescent wave of extraordinary beam at uniaxial crystal surfaces

“…Evanescent wave fiber-optic biosensors, which are on the basis of evanescent wave principle, represent the next generation of cutting-edge technology with the potential of rapidly detecting and identifying microorganisms, toxins, allergens, and other analytes of interest [4] . Along with the vast using amount of optical polarization elements, the need of studying the propagation of light in crystals is increasing progressively [5,6] . But the current discussion of light is much more in bireflection and birefringence of uniaxial crystals [7][8][9] than that in evanescent wave of extraordinary beam at crystal surfaces.…”
