Optoelectronic Devices and Integration VIII.
Epitaxial growth of a high-quality InSb layer on a mismatched substrate which provides a path to monolithically integrate InSb-based photonic devices and Si/GaAs-based electronic devices on a single wafer. This work is an attempt to investigate the e

We recently evaluated the optical and electric characteristics of mid-wave photodetector (PD) diodes grown on high-index substrates. Preliminary results indicate that substrate orientation and surface polarity can modify PD parameters such as photolu

Reduction of dark current density in microjunction-based InAs/InAs1-xSbx type-II superlattice long-wavelength infrared photodetectors was demonstrated. A double electron barrier design was used to suppress both generation-recombination and surface da

Fe2+:Cd1-xMnxTe solid solution spectroscopic and lasing properties depending on temperature and Mn concentration x were investigated. A set of Fe2+:Cd1-xMnxTe crystals with different concentration of Mn (x = 0.1, 0.52, 0.68, and 0.78) was synthesized

One of JAXA’s future missions, using an imaging Fourier Transform Spectrometer (FTS), requires the focal plane array (FPA) that has high sensitivity up to the very long-wavelength infrared (VLWIR) region. Since a Type-II superlattice (T2SL) is the

The goal of this work was an investigation of the temperature influence (in range 77 - 300 K) on laser properties of Tm:SrF2-CaF2 solid-solution, which is suitable as a gain medium for generation of radiation at 1.8-2 μm. The tested Tm:SrF2-CaF2 sam

High sensitive Terahertz detection can be achieved by properly constructing Metal-Semiconductor-Metal (MSM) structure with semiconductor materials. In this study, Mercury-Cadmium-Telluride (MCT) film was used to fabricate MSM Terahertz detectors. The
