Optical modulation and switch are crucial in photonics technologies, and microscope
electron sources are essential in imaging. However, it is an obstacle to integrating those …

We calculate the dielectric function and plasmonic response of armchair (aGNRs) and
zigzag (zGNRs) graphene nanoribbons using the self-consistent-field approach within the …

Atomically thin layers of transition metal dichalcogenides (TMDCs) exhibit exceptionally
strong Coulomb interaction between charge carriers due to the two-dimensional carrier …

Using the density-matrix formalism, we show that graphene nanomeshes (GNMs)—
graphene sheets patterned with antidots—have large plasmon-enhanced nonlinear optical …

Motivated by recent demands of the nanoplasmonic community, quasi-one-dimensional
nanoribbons have attracted significant attention as promising materials in logic applications …

Nonlinear nanophotonics has many potential applications, such as in mode locking,
frequency-comb generation, and all-optical switching. The development of materials with …

Full ranges of both hybrid plasmon-mode dispersions and their damping are studied
systematically by our recently developed mean-field theory in open systems involving a …

We present a quantum transport simulation of a 4.6-μ m quantum cascade laser (QCL)
operating at high power near room temperature. The simulation is based on a rigorous …

The development of nanomaterials with a large nonlinear susceptibility is essential for
nonlinear nanophotonics. We show that transition metal dichalcogenide (TMD) …

We derive a Markovian master equation for the single-electron density matrix, applicable to
quantum cascade lasers (QCLs). The equation conserves the positivity of the density matrix …
