Germanium-tin alloys: applications for optoelectronics in mid-infrared spectra
Journal Title: Opto-Electronic Advances - Year 2018, Vol 1, Issue 3
Abstract
We summarize our work of the optoelectronic devices based on Germanium-tin (GeSn) alloys assisted with the Si3N4 liner stressor in mid-infrared (MIR) domains. The device characteristics are thoroughly analyzed by the strain distribution, band structure, and absorption characteristics. Numerical and analytical methods show that with optimal structural parameters, the device performance can be further improved and the wavelength application range can be extended to 2–5 μm in the mid-infrared spectra. It is demonstrated that this proposed strategy provides an effective technique for the strained-GeSn devices in future optical designs, which will be competitive for the optoelectronics applications in mid-infrared wavelength.

Recent improvement of silicon absorption in opto-electric devices
Silicon dominates the contemporary electronic industry. However, being an indirect band-gap material, it is a poor absorber of light, which decreases the efficiency of Si-based photodetectors and photovoltaic devices. Th...
Compact pulsed thulium-doped fiber laser for topographical patterning of hydrogels
We report the generation of high energy 2 μm picosecond pulses from a thulium-doped fiber master oscillator power amplifier system. The all-fiber configuration was realized by a flexible large-mode area photonic crystal...
History, current developments, and future directions of near-field optical science
This paper reviews the science of the optical near-field (ONF), which is created and localized in a nanometer-sized material (NM) or on its surface. It is pointed out that work on near-field optics was started in order t...
Iterative freeform lens design for prescribed irradiance on curved target
Current freeform illumination optical designs are mostly focused on producing prescribed irradiance distributions on planar targets. Here, we aim to design freeform optics that could generate a desired illumination on a...
Passively Q-switched Tm/Ho composite laser
We explored Q-switching mechanism for the newly proposed Tm/Ho composite laser via developing a hybrid resonator for separating the intra-cavity Tm laser modulated by the saturable absorber (SA). With a Cr:ZnSe SA, succe...
