Abstract
In this paper, we designed a thermo-optic variable
optical attenuator (VOA) based on quartz substrate, which consists of a
Mach-Zehnder interferometer (MZI) and a thin film heater above the
phase-modulation arm. The transmission properties of the waveguide and
attenuation characteristics of the device have been simulated by beam
propagation method (BPM), and the simulated results illustrated that the
designed VOA had good performance.
