Taschenbuch. Condition: Neu. Neuware - A fabrication process for PFCB waveguide air-trench bends on silicon substrate with electron beam lithography (EBL) and autoalignment has been developed and a high efficiency air-trench bend (97.2% for TE polarization and 96.2% for TM polarization) has been demonstrated. The simulation predicts an optical efficiency of 98.5% for TE and 98.2% for TM when the Goos Hanchen shift is properly accounted for. We have adapted this process to making air trench bends in PFCB waveguides on polyimide substrates. Compared to silicon substrates, the polyimide substrates have the advantage of less coefficient of thermal expansion (CTE) mismatch with PFCB films, which improves fabrication repeatability and yield.Using air-trench bends, an ultracompact 8 x 8 arrayed waveguide grating (AWG) demultiplexer (200 GHz) for WDM has been designed and fabricated on a polyimide substrate. Compared to a conventional AWG in the same material system, the air-trench bend AWG shrinks the required chip area by a factor of 20. The decreased size is a factor in reducing the measured thermal shift to -0.012 nm/C and decreasing the polarization-dependent wavelength shift to 1.3 nm.

Sonstige Video. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book collects papers from the 9th China Nuclear Power Plant Digital Technology and Application Seminar held in Ningbo, China in September 2025. This seminar aims to explore the software and hardware of digital and instrument control (I&C) systems in nuclear power plants, such as inspection, testing, certification and research of sensors, actuators and control systems, and the application of electrical and intelligent operation and maintenance technologies. It aims to provide a platform for experts, scholars and nuclear power practitioners to exchange technology and share experience. At the same time, it also provides a platform for the combination of universities and enterprises in the aspects of production, education and research, and promotes the safe development of nuclear power plants. In addition, readers will encounter new ideas to achieve more efficient and safer instruments and control systems.
