Enhanced Surface Second Harmonic Generation in Nanolaminates
Fatemeh Abtahi, Pallabi Paul, Sebastian Beer +6
Second-harmonic generation (SHG) is a second-order nonlinear optical process that is not allowed in media with inversion sym-metry. However, due to the broken symmetry at the surfa…
Atomically Thin Metal-Dielectric Heterostructures by Atomic Layer Deposition
Pallabi Paul, Paul Schmitt, Vilborg Vala Sigurjonsdottir +9
Heterostructures increasingly attracted attention over the past several years to enable various optoelectronic and photonic applications. In this work, atomically thin interfaces o…
Heterostructure films of SiO and HfO for high power laser optics prepared by plasma-enhanced atomic layer deposition
Shawon Alam, Pallabi Paul, Vivek Beladiya +11
Absorption losses and laser-induced damage threshold (LIDT) are considered as the major constraint for the development of optical coatings for high-power laser optics. Such coating…
Nonlinear polarization holography of nanoscale iridium films
Mouli Hazra, Pallabi Paul, Doyeong Kim +6
The phasing problem of heterodyne-detected nonlinear spectroscopy states that the relative time delay between the exciting pulses and a local oscillator must be known with subcycle…
Linear and Nonlinear Optical Properties of Iridium Nanoparticles by Atomic Layer deposition
Paul Schmitt, Pallabi Paul, Weiwei Li +10
Nonlinear optical phenomena enable novel photonic and optoelectronic applications. Especially metallic nanoparticles and thin films with nonlinear optical properties offer the pote…
Direct Growth of Monolayer MoS on Nanostructured Silicon Waveguides
Athira Kuppadakkath, Emad Najafidehaghani, Ziyang Gan +20
We report for the first time the direct growth of Molybdenum disulfide (MoS) monolayers on nanostructured silicon-on-insulator waveguides. Our results indicate the possibility…
