Larger width of P-cladding layer in p-i-n waveguide of traveling wave electroabsorption modulator (TWEAM) results in lower resistance and microwave propagation loss which provides an enhanced high speed electro-optical response. In this paper, a fullvectorial finite-difference-based optical mode solver is presented to analyze mushroom-type TWEAM for the first time. In this analysis, the discont...

Chatoyant is an opto-electro-mechanical CAD tool developed to meet the needs of systems designers.

LEDs are more commonly being used in optical systems due to the advances in LED technology in power, efficiency, cost and wavelength output; especially white light LEDs. Fresnel lenses are also cost effective and advancements in aspheric Fresnel lens manufacturing have made these lenses effective optical elements. Various optical design codes allow for accurate modeling of these incoherent ligh...

Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...

This paper describes the development of a novel microfluidic platform for multifactorial analysis integrating four label-free detection methods: electrical impedance, refractometry, optical absorption and fluorescence. We present the rationale for the design and the details of the microfabrication of this multifactorial hybrid microfluidic chip. The structure of the platform consists of a three...

This paper introduces the rationale for concrete situations in the authoring process that can exploit a theory-aware Authoring Environment. It illustrates how Ontological Engineering (OE) can be instrumental in representing the declarative knowledge needed, and how an added value in terms of intelligence can be expected for both authoring and for learning environments.
