The resonance features of the third-harmonic generation have been observed in 1D coupled microcavities consisting of three Bragg reflectors and two identical half-wave layers of mesoporous silicon. The third-harmonic intensity increases by a factor of about 10 3 in the resonance of fundamental ...

Optical third-harmonic generation (THG) is generally a weak process but is dipole allowed, therefore it occurs in all materials, including dielectric materials with inversion symmetry. We report that when using focused high-intensity ultrashort laser pulses, this normally weak THG process becomes high...

Optical Second and Third Harmonic Generation of Laser Beams in Nonlinear Media: A Review Nonlinear Optics, Quantum Optics: Concepts in Modern OpticsGUPTA, NAVEEN
Third harmonic (TH) generation by four-wave mixing is investigated in a novel design optical fiber. Numerical modeling predicts that TH conversion efficiency of 50% is achievable in the proposed fiber design. Experimentally demonstrated TH conversion efficiency is 2.5%. The main causes for lower tha...

Graphene Flagship researchers have shown for the first time gate tunable third harmonic generation in graphene. This research, led by Graphene Flagship Partner University of Cambridge, in Collaboration with Politecnico di Milano and IIT-Istituto Italiano
third harmonic generationthin filmsHighly-conjugated main chain polymers have been studied extensively in recent years as third order non-linear optical materials. However, in a non-centrosyinmetric system such as a polyene which has been substituted with an electron donor and acceptor group, the ...
