Femtosecond Z-scan measurements of nonlinear refraction in nonlinear optical crystals
We report an investigation of third-order optical nonlinearities in several nonlinear optical crystals using the Z-scan technique with femtosecond laser pulses at 780 nm wavelength. The crystals studied include LiNbO3:MgO, KTiOAsO4, KTiOPO4, b-BaB2O4 and LiB3O5, which are extensively used for ultrashort-pulse second-harmonic generation and optical parametric oscillation. The nonlinear refractiv...
متن کاملSingle photon nonlinear optics in photonic crystals
We coherently probe a quantum dot that is strongly coupled to a photonic crystal nano-cavity by scattering of a resonant laser beam. The coupled system’s response is highly nonlinear as the quantum dot saturates with nearly one photon per cavity lifetime. This system enables large amplitude and phase shifts of a signal beam via a control beam, both at single photon levels. We demonstrate photon...
متن کامل5 Negative Refraction in Photonic Crystals
The phenomenon of negative refraction (NR) by 2D photonic crystals (PCs) is demonstrated in microwave experiments. NR by PCs is observed in 2D parallel-plate waveguide and in 3D free space measurements. Results are in excellent agreement with band structure calculation and numerical simulation. The optical properties of isotropic materials that are transparent to electromagnetic (EM) waves can ...
متن کاملNegative Refraction and Imaging in Photonic Crystals
Negative refraction and left-handed electromagnetism in a photonic crystal are demonstrated in waveguide and free space experiments at microwave frequencies. Precision control to achieve tailor-made refractive indices has been achieved. The negative refraction in these photonic crystals is shown to lead to imaging by a flat lens. We have also developed a generalized theory of flat lens imaging....
