Perfect absorption by an atomically thin crystal
Jason Horng, Eric W. Martin, Yu-Hsun Chou +9
Optical absorption is one of fundamental light-matter interactions. In most materials, optical absorption is a weak perturbation to the light. In this regime, absorption and emissi…
Effect of Dimensionality on the Optical Absorption Properties of CsPbI Perovskite Nanocrystals
Albert Liu, Luiz G. Bonato, Francesco Sessa +7
The band-gaps of CsPbI perovskite nanocrystals are measured by absorption spectroscopy at cryogenic temperatures. Anomalous band-gap shifts are observed in CsPbI nanocubes…
Simultaneous Existence of Confined and Delocalized Vibrational Modes in Colloidal Quantum Dots
Albert Liu, Diogo B. Almeida, Wan-Ki Bae +2
Coupling to phonon modes is a primary mechanism of excitonic dephasing and energy loss in semiconductors. However, low-energy phonons in colloidal quantum dots and their coupling t…
Frequency comb generation at 800nm in waveguide array quantum well diode lasers
Chang Sun, Mark Dong, Niall M. Mangan +3
A traveling wave model for a semiconductor diode laser based on quantum wells is presented as well as a comprehensive theoretical model of the lasing dynamics produced by the inten…
Stable Numerical Schemes for Nonlinear Dispersive Equations with Counter-Propagation and Gain Dynamics
Chang Sun, Niall Mangan, Mark Dong +3
We develop a stable and efficient numerical scheme for modeling the optical field evolution in a nonlinear dispersive cavity with counter propagating waves and complex, semiconduct…
