Electrically pumped quantum-dot lasers grown on 300 mm patterned Si photonic wafers
Chen Shang, Kaiyin Feng, Eamonn T. Hughes +9
Monolithic integration of quantum dot (QD) gain materials onto Si photonic platforms via direct epitaxial growth is a promising solution for on-chip light sources. Recent developme…
Flexibility of Ga-containing Type-II superlattice for long-wavelength infrared detection
M. Delmas, D. C. M. Kwan, M. C. Debnath +2
In this paper, the flexibility of long-wavelength Type-II InAs/GaSb superlattice (Ga-containing SL) is explored and investigated from the growth to the device performance. First, s…
Material and device characterization of Type-II InAS/GaSb superlattice infrared detectors
M. Delmas, M. C. Debnath, B. L. Liang +1
This work investigates midwave infrared Type-II InAs/GaSb superlattice (SL) grown by molecular beam epitaxy on GaSb substrate. In order to compensate the natural tensile strain of…
Origin of the anomalous magnetic circular dichroism spectral shape in ferromagnetic (Ga,Mn)As: Impurity bands inside the band gap
K. Ando, H. Saito, K. C. Agarwal +2
The electronic structure of a prototype dilute magnetic semiconductor (DMS), Ga1-xMnxAs, is studied by magnetic circular dichroism (MCD) spectroscopy. We prove that the optical tra…
