Determining the optimum thickness for high harmonic generation from nanoscale thin films: An <i>ab initio</i> computational study

High-harmonic generation from an atomically thin semiconductor

High-harmonic generation (HHG) in bulk solids permits the exploration of materials in a new regime of strong fields and attosecond timescales. The generation process has been discussed in the context of strongly driven electron dynamics in single-particle bands. Two-dimensional materials exhibit distinctive electronic properties compared to the bulk that could significantly modify the HHG proce...

Resonant terahertz generation from InN thin films.

Highly efficient conversion from ultrafast optical pulses to their terahertz (THz) counterparts has been achieved with InN thin films. An average THz output power as high as 0.931 microW has been obtained for an average pump power of 1 W, corresponding to a normalized conversion efficiency of 190% mm(-2). Based on our measured dependences of the THz output power on pump polarization, incident a...

Efficient second harmonic generation from thin films of V-shaped benzo[b]thiophene based molecules.

We have designed an original approach for efficient Second Harmonic Generation of tailored V-shape benzo[b]thiophene molecular systems enabling versatile and flexible one-step, dry and technologically friendly thin film processing. The designed moieties show chi((2)) values at least as high as the reference LiNbO(3) single crystal, without poling processing and matching the constrains of integr...
