Abstract

This work presents the first possible realization of chip-scale liquid crystalline (LC) optoacoustic sensors that have the capability of detecting broadband acoustic signals via free-space coupling using white light input. The interaction between acoustic waves and the optical and mechanical properties of the LC molecular cavities was investigated. Systematic comparisons between a commercially available acoustic sensor system and the geometry-independent LC optoacoustic sensors are provided. This work will enable economical, compact, reliable, broadband, noncontact, and sensitive molecular-based acoustic sensors for use in various applications.
