Outline of Research at the Start

To develop ultra-small photonic integrated circuits for next-generation computing, the realization of a subwavelength nanolaser on-a-chip is a key challenge.
In contrast to conventional nanolasers based on nanowires, we demonstrate a 2D-/quantum dot-perovskite plasmonic nanolaser on-a-chip without needing to transfer nanowire lasers. The 2D-/QD-perovskites have been demonstrated for their high exciton binding energy and can be spin-coated on any substrate, which is very different from other gain materials requiring specialized growth technique and lattice-matched substrates.
