Abstract
In recent years a variety of cutting-edge nanophotonics technologies, such as plasmonics, photonic crystals, nano-wires, nano-particles, are extensively studied.They have already demonstrated various device performances surpassing those of conventional photonic devices based on ordinary materials. Most of these technologies are enabling ultrasmall photonic devices that can be densely integrated in a chip and consume a very small amount of energy per bit operation. Though many of them are still at the fundamental research level, they hold the promise to introduce large-scale photonics into a chip, such as MPU (micro-processing unit), thereby having an impact on future telecom/datacom. Therefore the time has come to hold a symposium specialized on nanophotonics technologies in ECOC. The purpose of this symposium is to present cutting-edge achievements in various areas of nanophotonics, and to shed light on their potential for future telecom/datacom. Especially, the objective is to clarify how these nanophotonics technologies will be able to solve problems confronting ICT (telecom/datacom) in the next 10 years. Six topics will be discusse, representing important fields in nanophotonics, covering several devices (lasers, switches, modulators, and detectors) based on plasmonics, photonic crystals, nano-wires, and nano-particles.


OPPORTUNITIES FOR METALLIC AND PLASMONIC NANO-LASERS IN OPTICAL COMMUNICATIONS
Martin T. Hill and Meint K. Smit, Eindhoven Univ. of Technology, The Netherlands
In theory nano-laser based on metallic/plasmonic cavities provide low power, high speed, and efficient nano-scale light emitters. Such devices may find application in short distance communications. We look at the possibilities and progress being made.


PLASMONIC NANOANTENNAS
Jaime Gómez Rivas, Center for Nanophotonics, Eindhoven Univ. of Technology, The Netherlands.
Light emission can be modified by the medium close to the emitter. Nanoparticles supporting surface plasmons lead to a strong modification of the directionally and efficiency of this emission and form nanosources with designable properties.


BURIED HETEROSTRUCTURE PHOTONIC CRYSTAL NANOCAVITY LASERS FOR PHOTONIC NETWORK-ON-CHIP APPLICATION
Shinji Matsuo, NTT Photonics Labs., Japan
High-speed directly modulated nanocavity laser is a key component for constructing a CMOS-integrated, on-chip photonic network. We develop ultracompact buried heterostructure photonic crystal lasers, in which InGaAsP-based active region is embedded within InP-based line-defect waveguide.


PHOTONIC CRYSTAL OPTICAL CIRCUITS FOR DATA SIGNAL PROCESSING
Alfredo De Rossi, Thales, France
Owing to their capability to confine light in a tiny volume, Photonic crystals have demonstrated their potential for optical data processing at ultra-low power. The Copernicus project aims at a WDM/OTDM photonic crystal chip.

HETEROEPITAXY OF INDIUM PHOSPHIDE ON SILICON FOR MONOLITHIC INTEGRATION
Sebastian Lourdudoss, Laboratory of Semiconductor Materials, Royal Institute of Technology, Sweden
An attractive platform for realizing monolithic integration of III-Vs on silicon for silicon photonics through Epitaxial Lateral Overgrowth (ELOG) is proposed, demonstrated and discussed.


COLLOIDAL NANOCRYSTALS AND THEIR POTENTIAL IN OPTICAL TELECOMMUNICATIONS
Vanessa Wood, ETH Zürich, Switzerland
Colloidally synthesized nanocrystals offer narrow bandwidth emission that can be selected across the visible and near-infrared wavelength regimes. Recent advances in the integration of colloidal nanoscrystals in optoelectronic devices highlight their potential for telcom applications. We review the benefits and challenges to realization of these technologies.
