Transfer Printing of Photonic Nanostructures to Silicon Integrated Circuits
Optical systems require the integration of technologies fabricated on different materials. We use a transfer printing technique to integrate pre-processed III-V, polymer and silicon membrane devices onto passive optical circuits with nano-metric positional accuracy
MEMS-enabled silicon photonic integrated devices and circuits
Photonic integrated circuits have seen a dramatic increase in complexity over the past decades. This development has been spurred by recent applications in datacenter communications and enabled by the availability of standardized mature technology platforms. Mechanical movement of wave-guiding structures at the micro- and nanoscale provides unique opportunities to further enhance functionality and to reduce power consumption in photonic integrated circuits. We here demonstrate integration of MEMS-enabled components in a simplified silicon photonics process based on IMEC's Standard iSiPP50G Silicon Photonics Platform and a custom release process
Gap and channelled plasmons in tapered grooves: a review
Tapered metallic grooves have been shown to support plasmons --
electromagnetically coupled oscillations of free electrons at metal-dielectric
interfaces -- across a variety of configurations and V-like profiles. Such
plasmons may be divided into two categories: gap-surface plasmons (GSPs) that
are confined laterally between the tapered groove sidewalls and propagate
either along the groove axis or normal to the planar surface, and channelled
plasmon polaritons (CPPs) that occupy the tapered groove profile and propagate
exclusively along the groove axis. Both GSPs and CPPs exhibit an assortment of
unique properties that are highly suited to a broad range of cutting-edge
nanoplasmonic technologies, including ultracompact photonic circuits,
quantum-optics components, enhanced lab-on-a-chip devices, efficient
light-absorbing surfaces and advanced optical filters, while additionally
affording a niche platform to explore the fundamental science of plasmon
excitations and their interactions. In this Review, we provide a research
status update of plasmons in tapered grooves, starting with a presentation of
the theory and important features of GSPs and CPPs, and follow with an overview
of the broad range of applications they enable or improve. We cover the
techniques that can fabricate tapered groove structures, in particular
highlighting wafer-scale production methods, and outline the various photon-
and electron-based approaches that can be used to launch and study GSPs and
CPPs. We conclude with a discussion of the challenges that remain for further
developing plasmonic tapered-groove devices, and consider the future directions
offered by this select yet potentially far-reaching topic area.Comment: 32 pages, 34 figure
