Magnetically induced transparency in helically structured periodic crystals.

We investigated the specific properties of magnetically induced transparency (MIT) and magnetically induced absorption (MIA) in helically structured periodic crystals (HSPCs). We showed that for the wavelength of MIT we have an ideal optical diode: The forward signal passes fully, while the backward signal is completely absorbed and not reflected. A formula for the wavelength λ_{t} of MIT and MIA resonance based on the numerical simulations was analytically obtained. The influence of HSPC parameters on the wavelength λ_{t} and on Δλ_{t}, the transparency line half width, was investigated by numerical simulations. The specific properties of light energy density, the ellipticity e_{in}, and azimuth φ_{in} of the total wave excited in the HSPC layer for MIT and MIA modes were investigated, too.
