Abstract
The far-infrared Cherenkov-type difference frequency generation (CDFG) in a planar optical waveguide is analyzed theoretically. The general expression for the CDFG angular distribution is given. The novel doubly resonant cavity is proposed. The CDFG efficiency enhancement due to resonant both at the optical and FIR frequencies is estimated to be a factor a few thousands.
