Fabry plane

A simple model that makes it possible to describe optical bistability in a variety of systems is a plane nonlinear Fabry-Perot interferometer, filled with a medium whose refractive index is intensity dependent [106]. The slow kinetics of a...

Measurements of the refractive index under pressure are necessary, in addition to the intrinsic refractive index as physical probes of condensed media, to interpret transmission measurements. This is most conveniently done under pressure by measuring Fabry-Perot interference patterns in plane-parallel samples. The position of the interference maxima in transmission is given by... 

The instrument most commonly used to resolve the Brillouin spectrum is the Fabry-Perot interferometer. This device consists of a pair of highly reflective, optically polished mirrors. The transmission function for a plane parallel Fabry-Perot interferometer is ... 

Another approach to MMW spectrometers is based on the Orotron This device, called after the Russian words for an open resonator and a reflection grating, was a semiconfocal Fabry-Perot cavity (Figure 5.1) with the plane mirror having a reflection grating ruled upon it. The cavity, with 0 lO, produced a spectral bandwidth without frequency locking 10-15 kHz and output power was 3-10 mW over 90-150 GHz.

The simplest implementation of an interferometric device is that of the so-called Fabry-Perot (FP) etalon. It consists of two plane-parallel, highly reflecting optical surfaces separated by some distance d, to form a wavelength-selective resonator, akin to that in lasers (see Chapter 3). The reflecting surfaces are formed by multilayer dielectric films on the surface of glass plates.

Fig. 5. Polarized Rayleigh-Brillouin spectrum of amorphous PnHMA taken with a Burleigh plane Fabry-Perot interferometer using a free spectral range of 12.4 GHz at 295 K. The two Brillouin peaks are shifted from the incident frequency by the product of the wave vector q and the sound velocity u. The line width of the Brillouin peaks is related to the attenuation of the sound waves. PnHMA.

A practical realization of the multiple beam-interference discussed in this section may use either a solid plane-parallel glass or fused quartz plate with two coated reflecting surfaces (Fabry-Perot etalon. Fig. 4.41a) or two separate plates, where one...
