Abstract

The fabrication of an optical cavity at the distal end of an optical fiber has been achieved by Langmuir–Blodgett (LB) deposition of tricosanoic acid. This technique allows nanometer-scale control over the cavity length to a total thickness of 0.5 μm. The cavity has been shown to act interferometrically and, thus, has potential sensing applications.
