We demonstrate that the localized introduction of cell markers by electroporation can be efficiently and safely achieved with reusable glass chips complying with industrial micromachining techniques. Consequently, any biologist can now rely on contract manufacturing to easily implement this transfection approach at moderate cost.
We demonstrate femtosecond supercontinuum generation in a silicon waveguide. Despite the strong nonlinear absorption inherent to silicon at telecom wavelengths, we experimentally demonstrate that the compression and subsequent splitting of higher order solitons remains possible.
The formation of self-confined beams using pyroelectric effect is numerically and experimentally studied in photorefractive LiNbO 3 . For a given crystal temperature change, the trapped beam width is shown to be less efficient as intensity is increased. Numerical calculations reveal that the induced refractive-index profile varies along propagation for large intensities due to a nonlinear...
