Hy. Ling, THEORETICAL INVESTIGATION OF TRANSMISSION THROUGH A FARADAY-ACTIVE FABRY-PEROT ETALON, Journal of the Optical Society of America. A, Optics, image science,and vision., 11(2), 1994, pp. 754-758
The multiple-beam summation method is used to construct a Fabry-Perot-
cavity theory that takes into consideration the Faraday rotation effec
t. The transmission functions and the state of the polarizations are d
erived and discussed for the resonant and the off-resonant cavity conf
igurations. The transmission function that includes the analyzer is al
so derived and discussed. The results in resonance configuration agree
with the early theoretical and experimental results: mainly that the
Faraday rotation can be resonantly enhanced by the Fabry-Perot cavity.
In the off-resonance configuration the transmission as a function of
the single-trip phase consists of two Airy functions separated by a di
stance of twice of the single-trip Faraday rotation. In the high refle
ctivity limit, the light at the peak becomes quasi-circularly polarize
d. The effect of this resonant structure on the Fabry-Perot cavity as
a spectroscopic tool is mentioned.
