TL;DR: In this article, the concept of photonic wire bonding is introduced, where transparent waveguide wire bonds are used to bridge the gap between nanophotonic circuits located on different chips.

TL;DR: In this article, a plasmonic photodetector achieving simultaneously record high bandwidth beyond 100 GHz, an internal quantum efficiency of 36% and low footprint is demonstrated, attributed to the subwavelength confinement of the optical energy in a photoconductive-germanium waveguide detector that enables shortest drift paths for photogenerated carriers and a small resistance-capacitance product.

TL;DR: The technical aspects of optical access solutions for mobile fronthaul application, including a WDM network with passive monitoring at the antenna site and automatic wavelength assignment based on self-seeded solution, are described.

TL;DR: In this paper, the authors review the SOH platform and discuss important devices such as Mach-Zehnder and IQ-modulators based on the linear electro-optic effect.

TL;DR: Optical waveguide mode-combiners for fundamental and first-order modes, based on multimode interference (MMI) couplers, are presented in this article, where a fundamental mode is converted into a transversal first order mode and combine it in lossless fashion with a second fundamental mode.
