We report experimental image reverse propagation in focusing Kerr media. These results are compared with a linear Zernike filter operation. A method for the measurement of the nonlinear coefficient is derived from these results. (C) 2010 Optical Society of ...

Compared to near infra-red photonic crystal (PhC) band-edge lasers, achieving vertical emission with quantum cascade (QC) material operating in the THz range needs dedicated engineering because the TM polarized emission of QCLs favors in-plane emitting sch ...
Brillouin scattering is particularly efficient and attractive for the implementation of strain and temperature distributed sensing in optical fibres. Recently a trend has been observed that modern advanced applications require a substantial step towards be ...
Lenses allow the formation of clear images in homogeneous linear media. Holography is an alternative imaging method, but its use is limited to cases in which it provides an advantage, such as three-dimensional imaging. In nonlinear media, lenses no longer ...
The coherent nature of second harmonic generation (SHG) makes possible retrieval of both its amplitude and its phase, by use of a proper phase-sensitive imaging technique such as digital holographic SHG microscopy. In addition to retrieving both amplitude ...
We describe and demonstrate a new oscillator topology, the parametric feedback oscillator (PFO). The PFO paradigm is applicable to a wide variety of nanoscale devices and opens the possibility of new classes of oscillators employing innovative frequencydet ...
We present the simulation, fabrication, and characterization of a metallic slot grating on a silicon waveguide (30nm slot width for a period of 500nm). According to the simulation, the experimental measured spectrum of the structure exhibits a dip in the n ...
The nonlinear optical properties of coumarin 343 (C343) dye-attached TiO2 nanoparticles in the size range 5-8 nm adsorbed at the interface of water/1,2-dichloroethane have been studied by using the surface second harmonic generation technique. No second ha ...
A simple approach is extended for the simulation of Kerr-nonlinear and/or dispersive media through the finite-difference time-domain method. The scheme is able to include different types of linear and nonlinear dispersion in a single and unified formulatio ...

Effect of relaxation time on the performance of photonic crystal optical bistable switches based on Kerr nolinearity is discussed. This paper deals with optical pulses with the duration of about 50 ps. In such cases the steady state response of the optical ...
