Abstract:
1. A method for receiving a radio frequency (RF) signal, comprising: using an all-dielectric RF antenna free of a metal to wirelessly receive an RF signal; coupling the RF signal received by the all-dielectric RF antenna into an all-dielectric RF waveguide free of a metal to guide the received RF signal away from the all-dielectric RF antenna; coupling the received RF signal in the all-dielectric RF waveguide into an all-dielectric RF resonator free of a metal that stores RF energy of the received RF signal that is coupled into the all-dielectric RF resonator; exposing an electro-optic material, which is free of a metal and exhibits an electro-optic effect, to the RF energy stored by the all-dielectric RF resonator; coupling continuous wave (CW) light into the electro-optic material to mix the CW light with the RF energy stored by the all-dielectric RF resonator to cause optical modulation of the CW light to produce modulated light that carries the RF signal; and processing the modulated light to extract the RF signal.
