Rectification, inversion, modulation, harmonic generation, and heterodyning are all effects
well known in the world of electronics as the essential properties of practical devices. These …

We review the principles and some recent advances in the theory of coherent control of
molecular processes and discuss some of its experimental realizations. Amongst the topics …

We provide a perspective overview of the emerging field of nonlinear optics in multimode
optical fibers. These fibers enable new methods for the ultrafast light-activated control of …

A large second-order nonlinearity [χ^(2)~ 1? pm/V~ 0.2? χ22 (2) for LiNbO_3] is induced in
the near-surface (~ 4 μm) region of commercial fused-silica optical flats by a temperature …

Quasi-phase-matching has long been a widely used approach in nonlinear photonics,
enabling efficient parametric frequency conversions such as second-harmonic generation …

We demonstrate room temperature coherent generation and control of a directional
photocurrent in bulk GaAs via simultaneous one-and two-photon interband absorption …

The direction of emission of photoexcited electrons in semiconductors is controlled by
adjusting the relative phase difference between a midinfrared radiation and its second …

We show theoretically that interband transitions in a bulk semiconductor via coherent one-
and two-photon absorption leads to the formation of an electrical current whose direction is …

Efficient second harmonic generation in integrated platforms is usually achieved by resonant
structures, intermodal phase-matching or quasi-phase matching by periodically poling …

As devices utilizing femtosecond-duration laser pulses become more commonplace, there is
a need for next-generation nonlinear-photonics technologies that enable low-energy …
