This paper reports the first experimental observation of "slow" pulse propagation in the exciton-polariton resonance of a direct-gap semiconductor. The propagation delay of short light pulses transmitted through a 3.7-\ensuremath{\mu}m-thick GaAs cry

The observation is reported of a remarkable persistence of the $1s$ exciton resonance in transient picosecond absorption spectra of GaAs under conditions of resonant optical excitation up to pair densities two orders of magnitude above the Mott densi

We report band edge absorption spectra of GaAs under conditions of high electron-hole pair excitation in the range of 10 13 -10 17 cm -3 achieved with picosecond light pulses tuned (i) to the 1s exciton energy and (ii) to the continuum (ω#62; E g ),

The reflectivity of single-crystal, orthorhombic GeS has been measured at 300\ifmmode^\circ\else\textdegree\fi{}K for all three polarizations in the photon energy range 0.1-30 eV. Eleven distinct peaks or shoulders are observed, about half of which c

The 1s-exciton absorption of GaAs is measured under conditions of fast transient resonant excitation with laser pulses of 8 psec duration and 1.2 meV bandwidth centered on the 1s-exciton line. The 1s-exciton remains stable up to pair densities exceed

We report the first experimental technique for compensating the pulse broadening in single‐mode optical fibers, using the ’’slow’’ anomalous pulse propagation in the exciton‐polariton resonance in a direct‐gap semiconductor. Mode‐lock

During the past few years the use of optical fibers has grown because of their potential application as transmission media in long-distance highbit-rate optical communication systems. Recently considerable attention has been given to the study of pul
