Abstract

A compact force fiber sensor capable of measuring forces at the piconewton level is reported. It consists of a miniature Fabry–Perot cavity fabricated at the tip a single-mode fiber, in which the external reflector is a compliant photonic-crystal diaphragm that deflects when subjected to a force. In the laboratory environment, this sensor was able to detect a force of only 4pN generated by the radiation pressure of a laser beam. Its measured minimum detectable force (MDF) at 3 kHz was as weak as 1.3pN/Hz. In a quiet environment, the measured noise was 16 times lower, and the MDF predicted to be 76fN/Hz.
