We demonstrate an optical hitless bypass switch based on nanomechanical proximity perturbation for high-bitrate transparent networks. Embedded in a single-level pi-imbalanced Mach-Zehnder interferometer, the two nanomechanical-based Deltabeta-directional couplers permit broadband signal rerouting on-chip, while the selected wavelength remains unaffected at all times for optical filter reconfigu...

-A new paradigm for an all-to-all optical interconnection network is presented. An interesting modeling aspect is that (limited) bending of optical communication channels is allowed. In a computer system, the paradigm could provide part of an interconnection fabric between several tens (e.g., 64) of chips comprising parallel processing elements and the first level of the cache. An optical inter...

Dust deposition to snow can have regionally important climatic and hydrologic impacts resulting from direct reduction of surface albedo and indirectly from the initiation of snow albedo feedbacks. Modeling the radiative impacts of dust deposited in snow requires knowledge of the optical properties of both components. Here we present an inversion technique to retrieve the effective optical prope...

Conceptual engineering design and optimization of laser-based imaging techniques and optical diagnostic systems used in the field of biomedical optics requires a clear understanding of the light-tissue interaction and peculiarities of localization of the detected optical radiation within the medium. The description of photon migration within the turbid tissue-like media is based on the concept ...

introduction: this study seeks to discuss the light wave transport characteristics variation along the pericardium meridian under different pressures. methods: we selected 36 healthy students at the school for this study, tied up the desktop blood pressure cuff onto subjects’right proximal arms, fixed the detection probe immovably on the neiguan (pc6) acupoint and the reference point which was ...

Injection molding is an important mass-production tool in the optical industry. In this research our aim is to develop a process of combining ultraprecision diamond turning and injection molding to create a unique low-cost manufacturing process for progressive addition lenses (PALs). In industry, it is a well-known fact that refractive index variation and geometric deformation of injection mold...

Modeling and simulation plays a very important role in the development of new technologies for manufacturing of integrated circuits. Optical projection printing is an excellent example of this activity which i9s described in this chapter. A brief introduction overviews the nature of characterization process and the role of modeling and simulation. The traditional experimentally driven character...

The proper operation and performance of optomechatronic systems is fundamentally affected by changes of the relative geometry caused by thermal influences, mechanical displacements and vibrations. Such extrinsic and intrinsic disturbances can be compensated by active control of optical elements like lenses, diffraction gratings or laser sources. In the context with system design and performance...

This work presents a study of the influence and compensation of aberrations in optical imaging systems by superimposing surfaces described by Zernike polynomials. The aim is to investigate how to compensate for aberrations and their effectiveness when dealing with aberrations of different types. The study is done in the Zemax packet by modeling the optical imaging system and passing test images...

In this paper, physical modeling including optical and Casimir forces is adopted in order to analyze a nano-opto-mechanical actuator based on silicon-on-insulator suspended slot waveguides. Numerical simulations based on the finite element method and systematic design rules are presented. Moreover, parametric investigations on slot waveguide sizes and optical properties are presented, and their...
