Nonlinear switching dynamics in a photonic-crystal nanocavity

Photonic crystal nanocavity array laser.

We demonstrate a new type of laser composed of an array of coupled photonic crystal nanocavities that enables high differential quantum efficiency and output power, together with a low threshold power comparable to those of single photonic crystal cavity lasers. In our experiment, the laser efficiency increases faster than the lasing threshold with an increase in the number of coupled cavities....

Magnetic light-matter interactions in a photonic crystal nanocavity.

We study the magnetic coupling between a metal-coated near-field probe and a photonic crystal nanocavity. The resonance of the nanocavity shifts to shorter wavelengths when the ringlike apex of the probe is above an antinode of the magnetic field of the cavity. We show that this can be attributed to a magnetic light-matter interaction and is in fact a manifestation of Lenz's law at optical freq...

Dipole-dipole interaction in a photonic crystal nanocavity

We put forward a general classical approach to obtain the quantum dipole-dipole interaction (DDI) between two two-level “atoms” in arbitrary nanostructures, in which the transfer rate of the DDI is analytically expressed as the difference between the two classical dipoles’ total radiation power and the sum of the two individual dipole’s radiation powers. The radiation power can be calculated by...

Electrically controlled modulation in a photonic crystal nanocavity.

We describe a compact modulator based on a photonic crystal nanocavity whose resonance is electrically controlled through an integrated p-i-n junction. The sub-micron size of the nanocavity promises very low capacitance, high bandwidth, and efficient on-chip integration in optical interconnects.
