The time delay properties of a Fabry-Perot interferometer are investigated. We found that the group velocity of light through a Fabry-Perot interferometer can b
GaInNAs/GaAs single-quantum-well (SQW) lasers have been grown by solid-source molecular beam epitaxy. N is introduced by a home-made dc-active plasma source. In
The experimental results show that the exchange coupling field Hex of NiFe/FeMn for Ta/NiFe/FeMn/Ta multilayers is higher than that for the spin valve multilaye
We report on a one-stage erbium-doped fibre amplified spontaneous emission (ASE) source with 80nm bandwidth and 13.5dBm output power. The broad bandwidth erbium
Thermal-induced interdiffusion in InAs/GaAs quantum dot superlattices is studied by high-resolution x-raydiffraction rocking curve and photoluminescence techniq
We study the three-dimensional magnetohydrodynamic (MHD) wave propagation in the solar atmosphere consisting of the chromosphere and corona. Pressure enhancemen
We theoretically study current self-oscillations and spatiotemporal current pattes in quantum-well negativeeffective mass (NEM) p+ pp+ diodes by considering sca
