Building manycore processor-to-DRAM networks using monolithic silicon photonics
FREE DOWNLOAD
Modern embedded systems already include dozens of cores on a single die and this number is expected to increase over the next decade. Corresponding increases in main memory bandwidth, however, are also required if the greater core count is to result in

Birefringence analysis of a photonics polymer doped with a birefringent crystal
FREE DOWNLOAD
ABSTRACT The purpose of this study is to design an optimal strontium carbonate (SrCO3) crystal which can effectively compensate the orientational birefringence of polymers. Additionally, we try to compensate large positive birefringence which polycarbonate (PC)

Nonlinear photonics in multi-dimensional and complex photonic lattices
FREE DOWNLOAD
ABSTRACT We review some of our recent results on experimental light-induced periodic structures and their role in controlling light in discrete optics considering advanced features based on phase engineering and multiplexing of optically-induced lattices. While in the

ABSTRACT Copper interconnects will soon be the limiting factor of the performance of a computer. The aim of Silicon Photonics is to bring the high performance of optical interconnects to silicon, a relatively cheap and abundant resource. Researchers at Intel

Electronics and photonics
FREE DOWNLOAD
Over the past five decades a steady increase in both the quantity and capability of electronic and photonic components that we may interact with on a daily basis has occurred. A stroll through an airport departure terminal at nearly any time of year effectively demonstrates

Integrated photonics based on planar holographic Bragg reflectors
FREE DOWNLOAD
ABSTRACT Integrated holographics is a novel photonics technology made possible by recent advances in semiconductor manufacturing technology and planar waveguide fabrication. The technology s corner stone, the holographic Bragg reflector (HBR), is a slab

Broadband terahertz wave generation, detection and coherent control using terahertz gasphotonics
FREE DOWNLOAD
Terahertz (THz) gas photonics uses gas as THz emitter and sensor for time-domain spectroscopy. Unique properties of the gas promise scalable, strong THz wave generation with broad spectral range covering the entire THz gas (0.3 THz to 35 THz). The systematic

Fabrication of sol-gel-derived optical waveguide on InP for hybridized photonics applications
FREE DOWNLOAD
ABSTRACT. In this paper, we report on the first successful fabrication, using spin-coating and low-temperature (200° C) annealing, of organically modified sol-gel planar optical waveguides on InP substrates. Considering the fact that the sol-gel technique is simple

RF Photonics for Lidar Systems: Optically Pre-Amplified Dual-Frequency Lidar-Radar
FREE DOWNLOAD
Different types of architectures are commonly used for the electromagnetic detection and identification of targets. On the one hand, the incoherent lidar concept, based on the direct detection and analysis of the light backscattered by the target, has demonstrated

The Global Photonics Education Network: Another way to think globally and act locally
FREE DOWNLOAD
ABSTRACT As the world gets smaller through globalization and telecommunication, it also gets richer in possibilities. Empowering the educators to exchange ideas on successes and mistakes continually on the global stage while working to improve the education on their

Photonics for phased array systems
FREE DOWNLOAD
ABSTRACT In the last several years, there have been significant advances in photonics for phased arrays. In this paper we present results in two key areas: 1) For receive-only arrays, we report on improvements in analog fiber links that have resulted in new records for the

Novel fabrication techniques for silicon photonics
FREE DOWNLOAD
ABSTRACT In this paper we report two novel fabrication techniques for silicon photonic circuits and devices. The techniques are sufficiently flexible to enable waveguides and devices to be developed for telecommunications wavelengths or indeed other wavelength

Optically-synchronized encoder and multiplexer scheme for interleaved photonics analog-to-digital conversion
FREE DOWNLOAD
Abstract Photonics Analog-to-Digital Converters (ADCs) utilize a train of optical pulses to sample an electrical input waveform applied to an electrooptic modulator or a reverse biased photodiode. In the former, the resulting train of amplitude-modulated optical pulses

The concept of modes in optics and photonics
FREE DOWNLOAD
ABSTRACT The concept of modes, or eigenfunctions, is fundamental for all wave phenomena in physics like optics, acoustics and quantum mechanics. In optics and photonics, the concept of modes is well suited to describe emission and absorption,

Photonics education and training in Ontario, Canada: an integrated plan
FREE DOWNLOAD
ABSTRACT Canada has established itself as a leader in photonics. Ontario in particular– home of giants such as JDS Uniphase, Nortel Networks, GSI Lumonics and an increasing number of successful start-up companies–has seen the demand for highly-qualified

Slow light fiber systems in microwave photonics
FREE DOWNLOAD
ABSTRACT Slow light systems are particularly attractive for analog signal processing, since their inherent limitation to a delaybandwidth product of 1 is less critical for analog systems such as those used in microwave photonics. We present here the implementation of two
