Integrated ultra-low-loss waveguides are highly desired for integrated photonics to enable applications that require long delay lines, high-Q resonators, narrow filters, etc. Here, we present an silicon waveguide on 500 nm thick Silicon-On-Insulator (SOI) platform. Meter-scale million-Q resonators and tens of picometer bandwidth grating filters experimentally demonstrated. We design a low-loss low-reflection taper seamlessly integrate the with standard heterogeneous Si/III-V platform allow...
Integrated photonics has profoundly impacted a wide range of technologies underpinning modern society. The ability to fabricate complete optical system on chip offers unrivalled scalability, weight, cost and power efficiency. Over the last decade, progression from pure III-V materials platforms silicon significantly broadened scope integrated by combining lasers with high-volume, advanced fabrication capabilities commercial electronics industry. Yet, despite remarkable manufacturing...
Samll conjugated dienes serve as one of the prototypical reactants in Diels-Alder cyclization reaction commonly used organic chemistry.These exhibit an interesting conformational landscape where lowest energy conformer is a trans conformation with gauche lying 10-15 kJ/mol higher energy.The has only recently been unambiguously indentified non-planar structure 1,3-butadiene (the simplest diene) by microwave spectroscopy.[1] We are interested understanding effect addition functional groups on...
