Photonic Bandgap structures are proposed for the design of the coupler of a 346 GHz sheet-beam backward wave oscillator. The design solves for typical issues of THz vacuum electron devices based on large sheet beams.
We investigate optomechanical effects in photonic crystal slab membranes, either including a cavity or acting as an end-mirror in a Fabry-Perot cavity. We in particular demonstrate the non-linear behavior of the membranes fundamental mode.
We overview recent advances in nanophotonics devices with emphasis on quantum dot lasers. The discussion includes high-performance quantum dot lasers and light-matter interaction in a single quantum dot with photonic crystal nanocavity. A single artificial atom lasers with two-dimensional photonic crystal nanocavity is demonstrated. Moreover, lasing oscillation in a quantum dot-three-dimensional photonic...
We present a coupled-wave analysis for square-lattice photonic crystal lasers with transverse electric polarization. A model consisting of eight plane waves coupled by Bragg diffraction is used to describe two-dimensional optical coupling. The resonant frequencies and threshold criteria for the modes of oscillation have been determined for the case of index periodicity with a lattice of circular holes...
We propose and investigate two-dimensional photonic-crystal lasers with a centered-rectangular lattice, which spans the lattice structure between the conventional square and triangular lattices.
We discuss recent advances in light-matter interaction in a single quantum dot embedded with photonic crystal nanocavity, including demonstration of a transition from strong coupling regime to lasing oscillation by the single dot gain.
Interaction of localized plasmons and propagating waveguide modes leads to strong coupling and polariton formation. These polaritons are the basis of nanoplasmonic effects in linear and nonlinear optics. Experiments, theory, and applications are presented.
We discuss a realistic photonic band-gap cavity using a field-emitter bound state. Such a cavity does not require a localized defect. It exists only in a strong-coupling regime, and it exhibits a very high Q-factor.
