in this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled inas/gaas quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. the microcavity wafer sample is grown by molecular beam epitaxy (mbe) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

We propose and demonstrate a two dimensional/three dimensional hybrid channel AlGaN/GaN high electron mobility transistor (HEMT) structure with a flat transconductance profile using polarization-induced channel engineering. A quasi three dimensional electron gas profile with 5–6 nm of vertical channel depth was formed by grading the channel region linearly from GaN to Al0.15Ga0.85 N over 50 Å. ...

Although autism is a behaviorally defined disorder, many studies report an association with increased pro-inflammatory cytokine production. Recent characterization of the BTBR T+tf/J (BTBR) inbred mouse strain has revealed several behavioral characteristics including social deficits, repetitive behavior, and atypical vocalizations which may be relevant to autism. We therefore hypothesized that,...

Abstract Multiplexing holography with metasurfaces using different degrees of freedom light has enabled recent applications in display and information processing. In terms polarization‐multiplexed holograms, the most general form is an arbitrary Jones matrix profile storing maximum amount information. It requires a relaxation to bianisotropic from conventional single‐layer implementation nanost...

We study analytically and numerically soliton communication links made by use of dispersion-decreasing fibers and parametric amplif iers. We show that bit rates greater than 100 Gbits/s (one channel, one polarization) can be achieved with large amplif ier spacings (as high as 120 km). The Raman effect and soliton interactions are compensated through optical phase conjugation, whereas fiber loss...
