Photon polarization oscillations

Решетов Владимир Александрович, Igor V. Yevseyev

The polarization properties of photon echoes in strong magnetic field, when the action of this field during the time of propagation of the exciting pulses and the echo signal through the resonant gaseous medium cannot be neglected, are studied theoretically. The photon echo polarization in strong magnetic field cannot be described by the polarization vector but rather by the polarization matrix. The degree of the photon echo polarization decreases with the increase of the magnetic field strength. The dependence of the photon echo intensity on the magnetic field strength was also analyzed numerically. In strong magnetic field the fast oscillations of this intensity appear to be damping and modulated by the slower ones. The spectrum of these oscillations depend also on the spectra of the exciting pulses, so that in case of small area of the first exciting pulse its temporal shape may be reconstructed from the oscillations of the echo intensity versus the magnetic field strength.

There is a straightforward correspondence between superposition of polarization modes of photons and that of classical radio waves. While classical particles cannot be superpositioned, classical waves can be, which is within classical intuition. Even more intuitively, two dimensional oscillations of a pendulum represent oscillating binary quantum state such as polarization state of photons.

We report the design of a polarization splitter based on two-photon Rabi oscillations in a three waveguide directional coupler. We show the practical feasibility of the device by carrying out simulations in lithium niobate waveguides.
