Abstract

We propose an innovative approach to fabricate microlasers by using nanoparticles and advanced self-assembly technique. The silica-based high-Q-factor porous microcavity is formed in the self-assembled process, then dye gain materials infiltrate into the cavity to support stimulated radiation. The laser spectrum has multiple peaks at ~600 nm waveband with threshold as low as 28 uJ/pulse.
