Novel resonance-based silicon nanophotonic structures

Numerical Simulation of Optoelectronic Devices, 2010
The development of ultra-compact integrated nanophotonic structures for communications, sensing, and signal processing has been of great interest lately. In this review paper, we first present the requirements for practical realization of integrated nanophotonic chips and then explain how these requirements are met by using low-loss waveguides and high

Nanophotonics in silicon-organic hybrid structures

SPIE Proceedings, 2009
Two dimensional photonic crystal waveguides in high index materials enable integrated optical devices with an extremely small geometrical footprint on the scale of micrometers.1-3 Slotted waveguides are based on the guiding of light in low refractive index materials and a field enhancement in this particular region of the device.

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.

Nanophotonic phase noise filter in silicon

Nature Photonics, 2020
Narrow-linewidth light sources have far-reaching applications from communication1 to metrology2–4. Benchtop linewidth reduction methods such as feedback5,6 and feed-forward7,8 schemes have been used to reduce the linewidth of lasers. The feedback scheme typically has a limited bandwidth and depends on the laser characteristics and the feed-forward ...

Polaritonics for silicon nanophotonics (Invited Paper)

SPIE Proceedings, 2005
Negative dielectric planar waveguides is reviewed toward silicon nanophotonics from the point of view of two-dimensional optical waves. Excitation, index-guiding, squeeze of optical beam width, adiabatic mode conversion of two-dimensional optical waves are discussed theoretically. The efficient excitation method of surface plasmon polariton is proposed

Passive and Active Silicon Nanophotonic Circuits

Frontiers in Optics, 2005
We will review results on nanophotonic circuits based on photonic crystals and photonic wires. Strong light confinement permits dramatic scaling of the active device area below 100μm2 with reduced operation power and increased efficiency.

Silicon nanophotonics : nanolasers with a twist

Nature Photonics, 2011
Optics is widely considered to be the best solution for coping with the growing information traffic found inside increasingly complex electronic processors and circuits. In particular, it is believed that the speed bottleneck inside and between processor chips will significantly impede further growth in the field electronics1. One of the major research

Silicon nanophotonic devices for integrated sensing

Journal of Nanophotonics, 2009
The potentials of a nanophotonic platform, including compactness, low power consumption, integrability with other functionalities, and high sensitivity make them a suitable candidate for sensing applications. Strong light-matter interaction in such a platform enables a variety of sensing mechanisms, including refractive index change, fluorescence ...
