Abstract
A frequency‐tunable terahertz (THz)‐frequency electromagnetic‐pulses generation method is proposed based on an optical Fabry–Perot (FP) microresonator with variable birefringence materials. At the output FP microcavity, polarization mode beat with high‐frequency can be achieved due to the phase mismatch effect of the two polarization modes in the birefringence materials in the FP cavity. One can generate frequency‐tunable electromagnetic pulse radiation through changing the birefringence of the materials. When the birefringence changed from 3.7355 × 10^−4^ to 7.4710 × 10^−2^, electromagnetic‐pulses with frequencies from 0.05 to 10.0 THz can be obtained. © 2011 Wiley Periodicals, Inc.
