In this paper, a novel optical generation of millimeter waves based on the birefringence in a single-mode fiber ring cavity is proposed and investigated theoretically. The input pulsed laser stimulates two orthogonal eigen-modes in a single-mode fiber ring cavity, the birefringence of single-mode fiber causes a phase mismatch for the two eigen-modes, this phase mismatch leads the generation of millimeter waves, out of the ring cavity a pigtail polarizer is used to combine the two eigen-modes, and then the millimeter wave signal is obtained by using heterodyne method. The effects of straight- through coupling coefficients, phase delay factor, and refractive index difference on millimeter wave signal are discussed.
