High repetition-rate pulse generation for millimeter-wave pulse signal by two cascaded Gires-Tournois Interferometers

A simple optical approach is proposed to obtain millimeter-wave (MMW) pulse signal by the high repetition-rate pulse generation in two cascaded Gires-Tournois Interferometers (GTIs). Compared with single GTI, the cascaded GTIs can optimize the MMW pulse envelope and improve the performance of radio frequency (RF) signal by adjusting the space of cascaded GTIs to change the reflection times of optical propagating signal. The primary influences for the cascaded GTIs on MMW pulse are analyzed theoretically and measured experimentally. It is shown that the good agreement between experimental results and theoretical simulations verifies the feasibility and flexibility of the proposed scheme.
