Abstract

High order Bessel beams (HOBBs) carrying discrete orbital angular momentum (OAM) are currently being explored for use in applications ranging from optical trapping to high-speed communication, all of which would benefit from the availability of compact semiconductor lasers with direct HOBB output. Here, we use an organic semiconductor gain medium to demonstrate a bilayer microdisk laser architecture that yields cylindrical vector HOBB emission with OAM quanta per photon >400h. These devices feature azimuthally polarized, few-mode lasing with optical pumping thresholds <100 μJ/cm2 and emission wavelengths that can be tuned over a range of ∼40 nm by varying the organic microdisk thickness. Our approach is generally applicable to organic and inorganic semiconductors alike and may therefore serve as a practical route for integrating HOBB functionality into a range of optoelectronic and photonic applications throughout the visible and near-infrared spectrum.
