TL;DR: The current state-of-the-art of optical couplers for photonic integrated circuits is reviewed, aiming to give to the reader a comprehensive and broad view of the field, identifying advantages and disadvantages of each solution.

TL;DR: The Roadmap is organized so as to put side by side contributions on different aspects of optical processing, aiming to enhance the cross-contamination of ideas between scientists working in three different fields of photonics: optical gates and logical units, high bit-rate signal processing and optical quantum computing.

TL;DR: These results represent the best performance ever reported in the literature for SOI structures without the use of any back-reflector.

TL;DR: This work proposes an alternative CMOS-compatible platform, based on silicon-rich silicon nitride that can overcome this limitation of nonlinear silicon photonic devices, and shows that both of the device linear and nonlinear properties can be tuned in order to exhibit the desired behaviour at the selected wavelength region.

TL;DR: In this paper, the effect of the SiH4 flow, RF power, chamber pressure and substrate on the structure, uniformity, roughness, deposition rate, refractive index, chemical composition, bond structure and H content of NH3-free PECVD SiN x layers was investigated.
