This paper discusses nanoscale engineered metal-dielectric-semiconductor resonant gain geometries confined in all three dimensions used to create a new type of nanolasers and light emitters. When these emitters are driven in a pulsed regime, dynamic hysteresis is observed and characterized.
The integration of a photonic information processing system onto a single chip requires great research effort toward engineering metamaterials for miniaturization of the optical devices and circuits. We discuss nanoscale engineered optical nonlinearities for modulation and wave mixing of optical fields, and metal-dielectric-semiconductor nanostructures and compositions to construct nanoemitters for...

Dual-frequency solid-state lasers are attractive for a large number of applications such as microwave photonics, spectroscopy, and metrology. As far as dual-frequency lasers are considered, the intensity noise spectrum of each eigenmode exhibits two peaks lying at the well-known in-phase and anti-phase eigen-frequencies of two coupled oscillators. The in-phase noise, which corresponds to the standard...
Strong anti-phase intensity noise reduction is experimentally and theoretically shown for dual-frequency Nd:YAG lasers. This phenomenon is obtained by aligning the two orthogonally polarized modes along the crystallographic axes of a (100)-cut Nd:YAG crystal.
We have experimentally and theoretically explored the degree of correlation of intensity noises of two orthogonally polarized modes in a dual frequency VECSEL for different values of coupling by changing spatial separation between the modes.
Coherent population oscillations (CPO), an ubiquitous mechanism inducing slow and fast light (SFL), is present in any active medium provided that a strong optical beam saturates this medium. Thus, CPO must be present in any single frequency laser since the oscillating beam acts as a strong pump which saturates the active medium. This effect could be observed using an external probe whose angular frequency...
The role of coherent population oscillations is evidenced in the noise spectrum of an ultra-low noise laser. The coherent population oscillations manifest themselves through their associated dispersion probed by the non-lasing side modes.
We study a Fabry-Perot cavity formed from a ridge waveguide on a AlGaAs substrate. We experimentally determined the propagation losses in the waveguide at 780 nm, the wavelength of Rb atoms. We have also made a numerical and analytical estimate of the losses induced by the presence of the gap which would allow the interaction of cold atoms with the cavity field. We found that the intrinsic finesse...
