Tunable 1D Photonic Crystal Nanolaser and its Capability of Stretching Sensing

Abstract

Tunable nanolasers via 1D nanoblocks embedded within polydimethylsiloxane are demonstrated, which show large wavelength tunability of 7.65nm per 1% stretching and high reliability under repeating stretching/ relaxing tests. Wide tuning range over 80nm is achieved. As a stretching sensor, minimum detectable stretching of 0.072% is obtained.
