Grafting fluorescent nanodiamonds onto optical tips

We recently introduced an all-optical method for grafting onto the apex of an optical tip a single 20 nm nanodiamond with single color-center occupancy and used the resulting single-photon tip in scanning near-field imaging at room temperature,…

Observation of Slow Light in the Noise Spectrum of a Vertical External Cavity Surface-Emitting Laser

The role of coherent population oscillations is evidenced in the noise spectrum of an ultralow noise laser. This effect is isolated in the intensity noise spectrum of an optimized single-frequency vertical external cavity surface-emitting laser. The…

Intermodulation distortion in microwave phase shifters based on slow and fast light propagation in semiconductor optical amplifiers.

We show theoretically and validate experimentally the effect of filtering on the nonlinear behavior of slow and fast light links based on coherent population oscillations in semiconductor optical amplifiers. The existence of a dip in the power…

Experimental demonstration of enhanced slow and fast light by forced coherent population oscillations in a semiconductor optical amplifier.

We experimentally demonstrate enhanced slow and fast light by forced coherent population oscillations in a semiconductor optical amplifier at gigahertz frequencies. This approach is shown to rely on the interference between two different…

Measurement of the coupling constant in a two-frequency VECSEL.

We measure the coupling constant between the two perpendicularly polarized eigenstates of a two-frequency Vertical External Cavity Surface Emitting Laser (VECSEL). This measurement is performed for different values of the transverse spatial…
