Second-Harmonic Generation in Suspended AlGaAs Waveguides: A Comparative Study
Micromachines, 2020 Due to adjustable modal birefringence, suspended AlGaAs optical waveguides with submicron transverse sections can support phase-matched frequency mixing in the whole material transparency range, even close to the material bandgap, by tuning the width-to ...

Polarization-resolved second-harmonic-generation optical coherence tomography in collagen [PDF]
, 2004 We describe a novel imaging technique, second-harmonic-generation optical coherence tomography (SHOCT). This technique combines the spatial resolution and depth penetration of optical coherence tomography (OCT) with the molecular sensitivity of second ...

Super/subradiant second harmonic generation [PDF]
Laser Physics Letters, 2017 A scheme for active second harmonics generation is suggested. The system comprises $N$ three-level atoms in ladder configuration, situated into resonant cavity. It is found that the system can lase in either superradiant or subradiant regime, depending on the number of atoms $N$.
