This invited paper overviews Corning® Willow™ Glass substrates and their enabling of new display and lighting applications, devices, and materials. Specific focus is put on flexible glass' mechanical reliability, R2R processing, and organic electronic devices.
High-Q performance in microcavities relies upon use of low absorption dielectrics and creation of smooth dielectric interfaces. For chip-compatible devices, silica has the lowest intrinsic material loss [1]. Microtoroid resonators combine this low material loss with a reflow technique in which surface tension is used to smooth lithographic and etch-related blemishes [2]. At the same time, reflow smoothing...
Due to limitations in device speed and performance of silicon-based electronics, silicon optoelectronics has been extensively studied to achieve ultrafast optical-data processing. However, the biggest challenge has been to develop an efficient silicon-based light source since indirect band-gap of silicon gives rise to extremely low emission efficiency. Although light emission in quantum-confined silicon...
Superconducting devices offer the potential to perform at speeds and detection efficiencies higher than what is possible using conventional technologies (such as semiconducting avalanche photodiodes and photomultiplier tubs) for wavelengths from the ultraviolet to the mid-infrared. As a result, there has been increasing interest in using superconducting optical photon detectors in a variety of applications...
We review high power semiconductor laser development at the Ferdinand-Braun-Institut, focusing on studies to improve material quality, design development for peak performance in standard structures and the development of novel device concepts for new applications.
In recent years, type-II InAs/GaSb superlattices (T2-SLs) have demonstrated dramatic advances and are a serious contender for the high performance infrared (IR) imaging market [1–2]. The improved understanding of the material properties, as well as the implantation of advanced device architectures, has substantially improved the device performance. Here we will report our efforts to develop mid-IR...
