Abstract
This paper proposes and demonstrates a new type of pressure sensor, using a metal-clad ion-exchanged glass waveguide with a liquid buffer layer. The thickness of the buffer layer is variable with pressure, which results in light intensity modulation of guided modes. In the tested waveguide pressure sensor in which water is used as the buffer layer, 80-% decrease of the output light intensity has been obtained with respect to an applied pressure of approximately 300 torr.
