Future bandwidth demand in optical communication and signal processing systems will
soon exceed 100 Gb s− 1 as is commonly forecasted from a throughput experience curve for …

Wireless, optical, and electronic networks continue to converge, prompting heavy research
into the interface between microwave electronics, ultrafast optics, and photonic …

We study the size dependence of the nonlinear response of weakly confined excitons for the
size region beyond the long wavelength approximation regime. The observed degenerate …

We derive a bosonized Hamiltonian describing two-exciton correlation of semiconductor-
photon coupled systems with a bosonization method, which takes into full account an effect …

We have theoretically demonstrated the drastic enhancement of light-induced electric
polarization in molecular nondipole type dark states. Its magnitude can exceed that of bright …

We report the observation of a remarkably strong coupling between light and a multinode-
type exciton. The observed radiative decay time reaches the order of 100 fs, which is much …

We investigated the third-order nonlinear response of excitons in GaAs thin films grown by
molecular beam exitaxy. Degenerate four-wave mixing (DFWM) measurements were made …

We report an ultrafast response of weakly confined excitons in GaAs thin films observed by a
degenerate four-wave-mixing (DFWM) technique. The time-domain signals excited by …

We study the mode structure of a size-dependent exciton–radiation coupled system by
means of nonlocal response theory. Considering excitons whose center-of-mass motion is …

The local-field distribution and optical absorption from the intersubband transitions in
semiconductor Pöschl-Teller quantum wells are investigated with the self-consistent-field …
