Abstract

We report optically pumped room-temperature lasing in a square-lattice photonic crystal cavity consisting of two shifted lattice points and heterogeneous lattices with different air hole sizes. Three-dimensional finite-difference time-domain simulation shows that this cavity has an ultrasmall mode volume of 0.017 μ m3 ∼1.7 (λ2 nslab)3. Photoluminescence spectroscopy exhibits pulsed lasing action at 1511 nm with a low lasing threshold of ∼130 μW. The measured Q factor is ∼2400 that is well agreed with the theoretical Q of 4200. In addition, the computational analysis based on the actual fabricated structural parameters unambiguously presents the successful demonstration of this ultrasmall lasing mode.
