D.W. and T.W.O. conceived the idea of engineering the band-edge modes for nanolasing with plasmonic nanoparticle superlattices. D.W. fabricated the devices, carried out the optical measurements, and performed FDTD numerical simulations of the band structure, near-field distribution and multi-moda...
We show rigorously that the topological gapless phase always hosts a partial Majorana flat band edge modes in a ribbon geometry, although such a single band model has zero Chern number as a topologically trivial superconductor. The flat band disappears when the gapless phase becomes topologically ...
We report the room-temperature lasing action from two-dimensional photonic crystal (PC) structures composed of a passive Si3N4 backbone with an over-coat of CdSe/CdS/ZnS colloidal quantum dots (CQDs) for optical gain. When optically excited, devices lased in dual PC band-edge modes, with th...
We demonstrate, theoretically and experimentally, that the modes of coupled cavities created in periodic waveguides can depend critically on the lateral shift between the cavities. In the absence of such shift, the modes feature symmetric or antisymmetric profiles, and their frequency splitting generally...
We identified the photonic bandgap-bandedge (PBG-BE) lasing modes through the spectral position, near-field pattern, and the state of polarization, which correspond well with the results of the three-dimensional (3D) finite-difference time-domain (FDTD) method computation. The two-dimensional (...
