Silicon nanophotonics

2012
AbstractSilicon nanophotonics deals with unique luminescence properties of silicon nanocrystals sized approximately from one to several nanometers. These nanocrystals have the potential to become active medium in future light-emitting devices or even in a silicon laser.

Silicon Nanophotonic Waveguide and Coupling

2008 IEEE PhotonicsGlobal@Singapore, 2008
Modal characterization of silicon nanophotonic waveguide and its coupling to an optical fiber are investigated, which include: 1) a full-vectorial modal analysis of silicon nanophotonic waveguide and a TM-pass nanophotonic polarizer based on a simple taper structure; 2) a superlens based coupling structure between nanophotonic waveguide and singlemode ...

Nanophotonic biosensors in silicon-on-insulator

2013 Transducers & Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS & EUROSENSORS XXVII), 2013
In this paper, two recent advances in silicon ring resonator biosensors are presented. First, we address the problem that due to the high index contrast, small deviations from perfect symmetry lift the degeneracy of the normal resonator mode. This severely deteriorates the quality of the output signal.

Nonreciprocal silicon-organic nanophotonic structures

SPIE Proceedings, 2011
We present a setup to measure the nonreciprocal magneto-optical phase shift in air and polymer cladded silicon on insulator waveguides. A high sensitivity could be achieved for the setup sufficient to determine the effect produced by silicon and silica.

3C Silicon Carbide Nanophotonics

Frontiers in Optics 2016, 2016
The development of novel photonic materials can offer new capabilities for non-linear and quantum optics. We demonstrate key components for a photonic platform in 3C-SiC, including high-confinement waveguides, grating couplers and high-Q resonators.

Hybrid silicon-ferroelectric oxide platform for tunable nanophotonics on silicon

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
In this communication, we present strategies to implement novel or enhanced optoelectronic functionalities on silicon via the monolithic integration of functional oxides as active layers for nanophotonic devices. We focus on the use of ferroelectric oxides with naturally strong electro-optical coefficients such as BaTiO 3 (BTO) on SOI for the ...

Dynamic Silicon Nanophotonics

2013
Abstract : Dynamic tuning of optical cavities enables rich new capabilities that operate with low power, are linear, efficient, compact and CMOS compatible. These dynamic devices are based on the fundamental principle that light propagating within a cavity must inherently match the properties of the cavity at all times.

Silicon- and plasmonics-based nanophotonics for telecom and interconnects

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
Silicon nanophotonics became recently a very promising solution for high-speed signal transmission and processing with high bandwidth and very compact size, even for multifunctional integrated structures. With submicron waveguide cross section and bending radius down to 2 mu m with acceptable losses (0.04 dB/90 degrees bend) these structures give ...

Nanophotonics silicon solar cells

2017
High-speed economic development in a modern society requires enormous energy consumption, in which electricity plays an important role. By the year 2040, the world energy consumption is predicted to boost to about 23 TW, which is mainly from the nonrenewable resources such as coal, oil, and gas, producing carbon dioxide (CO2) contributing detrimentally
