TuD1.1 - MID-IR ULTRAFAST LASER INSCRIBED WAVEGUIDES AND DEVICES

Abstract

Abstract

Ultrafast laser inscription(ULI) is a versatile technique for creating index modifications in glasses and crystalline materials. The process of ULI relies on ultrashort laser pulses focused inside of a material. The refractive index change obtained by ULI can be used to create waveguides and devices.

TuD1.2 - DEVELOPMENT OF GESN/SIGESN TECHNIQUE TOWARDS INTEGRATED MID-INFRARED PHOTONICS APPLICATIONS

Abstract

Abstract

GeSn optically pumped lasers and photodetectors have been investigated. The maximum operation temperature of 270 K was achieved for lasers. Spectral cut-off up to 3.6 µm was measured for detectors. Moreover, the mid-infrared images were obtained using photoconductors.

Abstract

Abstract

I will first discuss the unique properties of graphene including ultralow heat capacity and weak electron-phonon coupling strength. Leveraging these unique properties, I will present an efficient mid-infrared photodetector based on graphene plasmons operational at room temperature. Such photodetectors may find applications in high-speed thermal imaging and free-space communications.

Abstract

Abstract

Atom-like defect centers in wide-bandgap (WBG) materials with controllable quantum coherence have emerged as promising quantum emitters (QEs) and room-temperature qubit candidates. We discuss studies on QEs in two selected material platforms, silicon carbide (SiC) thin films and 2D hexagonal boron nitride (h-BN) crystals.
