There are planets having an atmosphere with permittivity which is high close to the planet surface and gradually decreases with elevation. Based on the results of our investigations when the light beam propagates parallel to the layers of atmosphere, its propagation direction is gradually deviating from the straight line toward higher permittivity layers. This way the light wave follows a curved route. The aim of the paper is to provide a qualitative picture for the phenomenon of light wave propagation bending around cosmic planets.

AB - A novel approach, an optical radio over fiber link with double polarization multiplexing is presented. In the two orthogonal polarizations of the optical beam the contents of information to be transmitted are different doubling the link capacity this way. For experimental verification a millimeter wave radio over fiber link with double polarization multiplexing has been developed. To ensure low cross polarization an incoherent approach is used. A high quality signal transmission is achieved by a proper procedure providing high polarization extinction ratio. In the experimental investigations different bit rates and fiber lengths are used. A signal with 12 Gbit/s bit rate is transmitted over a 25 km long link with about 1.10(-8) bit error rate. That result is much better than the already published data measured on experimental links.
