In this work, we present an experimental measurement of temperature and strain sensitivities of a micro-drilled optical
fiber (MDOF). The MDOF consisted of a quasi-randomly distributed reflector along a single mode fiber (SMF). A fiber
cavity laser based on MDOF was experimentally studied, attaining a single-wavelength laser emission centered at
1568.6nm. The output power level obtained from this single-laser oscillation when pumped at 140mW was around -
9.6dBm, and an optical signal to noise ratio (OSNR) of around 45dB was measured. Although temperature sensitivities
of fiber Bragg gratings used as sensors are similar to our MDOF, strain sensitivity is enhanced around one order of
magnitude when the MDOF was used.
