Characterization of Nonlinear Dynamics in Semiconductors in Frequency Domain using Modulated Photoexcitation
Attia Awan, Rong Tang, Zhou Kang +1
Carrier dynamics in semiconductors is inherently complex owing to the coexistence of different excited species, such as free carriers and excitons, and their interactions among the…
2D MoS/Au interfaces for enhanced opto-electronic response with sub-bandgap photons
Jinlei Wu, Wei Huang, Ahsan Ali +5
Monolayer MoS is a direct band gap semiconductor with potential applications in optoelectronics and photonics. MoS also has a large optical nonlinearity. However, the atomi…
Effects of impurity band on multiphoton photocurrent from InGaN and GaN photodetectors
Chuanliang Wang, Ahsan Ali, Jinlei Wu +3
Multiphoton absorption of wide band-gap semiconductors has shown great prospects in many fundamental researches and practical applications. With intensity-modulated femtosecond las…
Probing Silicon Carbide with Phase-Modulated Femtosecond Laser Pulses: Insights into Multiphoton Photocurrent
Ahsan Ali, Chuanliang Wang, Jinyang Cai +1
Wide bandgap semiconductors are widely used in photonic technologies due to their advantageous features, such as large optical bandgap, low losses, and fast operational speeds. Sil…
Decoding phase and time-dependent interferograms of high-order harmonics
C. Granados, Ching-Ling Hsiao, Marcelo F. Ciappina +1
Interferometric measurements of high-harmonics induced by multiple laser fields in an emerging field of research that promises optimized yield of harmonics, and time and space-reso…
Compressed Sensing for Reconstructing Coherent Multidimensional Spectra
Zhengjun Wang, Shiwen Lei, Khadga Jung Karki +2
We apply two sparse reconstruction techniques, the least absolute shrinkage and selection operator (LASSO) and the sparse exponential mode analysis (SEMA), to two-dimensional (2D)…
