Dielectric breakdown and sub-wavelength patterning of monolayer hexagonal boron nitride using femtosecond pulses
Sabeeh Irfan Ahmad, Emmanuel Sarpong, Arpit Dave +6
Hexagonal boron nitride (hBN) has emerged as a promising two-dimensional (2D) material for many applications in photonics. Although its linear and nonlinear optical properties have…
High-speed scanless entire bandwidth mid-infrared chemical imaging
Yue Zhao, Shota Kusama, Yuji Furutani +3
Mid-infrared spectroscopy probes molecular vibrations to identify chemical species and functional groups. Therefore, mid-infrared hyperspectral imaging is one of the most powerful…
Ultrafast Multi-Shot Ablation and Defect Generation in Monolayer Transition Metal Dichalcogenides
Joel M. Solomon, Sabeeh Irfan Ahmad, Arpit Dave +5
Transition metal dichalcogenides are known to possess large optical nonlinearities and driving these materials at high intensities is desirable for many applications. Understanding…
Ultrafast Laser Ablation, Intrinsic Threshold, and Nanopatterning of Monolayer Molybdenum Disulfide
Joel M. Solomon, Sabeeh Irfan Ahmad, Arpit Dave +7
Laser direct writing is an attractive method for patterning 2D materials without contamination. Literature shows that the femtosecond ablation threshold of graphene across substrat…
Pulsed THz radiation due to phonon-polariton effect in [110] ZnTe crystal
Chien-Ming Tu, Shin-An Ku, Wei-Chen Chu +3
Pulsed terahertz (THz) radiation, generated through optical rectification (OR) by exciting [110] ZnTe crystal with ultrafast optical pulses, typically consists of only a few cycles…
