Question

Which is the main wave interaction property used to filter wavelengths in a Fabry Perot Cavity or in Distributed Bragg Refractors ??

Answer 1

The property of difference in refractive index used to filter wavelengths in Fabry Perot cavity or in distributed Bragg Refractors.

The high-frequency spectrometer includes the first wavelength wedge filter order of order n1 specifying incoming radiation as linear function function, at least the second order of the wedge n2 (that region can be a distance measuring film). For other combinations, the second element of the dielectric wedge includes a Fabrey-Perot etalon, a dielectric wedge film, or a composite index film that covers the second region of the dielectric wedge and the base.
