摘要

我们最初的导波光学麦克风由一个膜片和一个单模光波导组成。灵敏度是麦克风的一项重要指标，理论上已知它与隔膜厚度有关。在本研究中，我们制作了三种不同膜片厚度的传声器，并通过实验研究了膜片厚度对传声器灵敏度的影响。

Diaphragm thickness-dependent sensitivity in a glass-based guided-wave optical microphone

Our original guided-wave optical microphone consists of a diaphragm and a single-mode optical waveguide. Sensitivity is an important specification for microphones, and is theoretically known to be dependent on diaphragm thickness. In this study, we fabricated three microphones with different diaphragm thicknesses, and experimentally examined the diaphragm thickness-dependent sensitivity.
