Defect laser behavior was simulated as a function of various parameters. When the crystal size was increased from 8/spl times/8 to 12/spl times/12 cylinders, the quality factor of the defect cavity increased from 6/spl times/10/sup 3/ to 5/spl times/

This numerical study investigated the possibility of using quantum disks in a gain-coupled distributed feedback (DFB) laser, specifically whether the laser would oscillate when the number of electrons in a disk (N/sub th/) is less than the maximum po

The normalized oscillation frequency /spl delta/L and threshold gain /spl alpha/L of gain-coupled distributed feedback (DFB) lasers with an AR/AR (symmetric) structure vary significantly with a variation in the corrugation phase at the facets when th

InGaAs-AlAsSb double and triple quantum well (QW) structures were designed in an effort to shorten the wavelength to less than 2 /spl mu/m for possible application to intersubband unipolar lasers. Wavelengths corresponding to the intersubband separat

Quantum-confined Stark effects (QCSE's) on excitons in semiconductor quantum disks with finite-potential barriers have been calculated as a function of disk size parameters by a variational calculation in an effort to examine possible application to

A thin GSO scintillator was developed aiming at applications for the neutron science. In order to fabricate a large and thin GSO scintillator in the future, fabrication was started from two types of GSO powders. Although several GSO films were fabric

Two kinds of InGaAs-InAlAs asymmetric coupled quantum wells (QW's) were numerically analyzed in an effort to enhance change in the refractive index (/spl Delta/n) at longer wavelengths where absorption coefficient is small. The analysis reveals the o

Numerical analysis predicts that the Stark effect will induce large blue shifts in three-step asymmetric quantum wells. These large blue shifts cannot be produced without a large net separation of electrons and holes at zero bias. Oscillator strength

In order to study the difference of uptake and distribution between hexavalent (Cr6+) and trivalent (Cr3+) chromium in isolated rat hepatocytes, the cells were incubated with Cr6+ or Cr3+ (1 mM Cr) at 37 degrees C for up to 60 min. Leakage of lactate
