Telecom vendors have traditionally provided the highest bandwidth for relatively lower volume applications and been able to charge a premium in price. Datacom vendors, on the other hand, have concentrated on lower bandwidth products that are used in high-volume applications and made available at very low prices. Parallel optics is unique in that it enables high-bandwidth by aggregating multiple lower-bandwidth channels and producing them in high-volume at a low price. This paper addresses the challenges of ramping up a parallel optical module in manufacturing.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

The parametric scaling of modal properties on cavity geometry including gain overlap, scattering and wing-clipping losses, in addition to diffraction, is obtained via an expansion of the round-trip matrix in G-L modes and subsequent diagonalization. Modal waist in laterally open cavities follows from the optimization for the round trip coefficient relative to /spl omega//sub 0/. Numerical values for the round trip modal losses are obtained through a fast numerical solution of the mathematical model equations, using the numerical algorithm PREVEU.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

This was a result of the core region have a confining effect on the mode. It was also determined that by adding another air-silica layer to the 4-layer structure, the fraction of evanescent power and power in the holes was increased for all values of a So, the ideal waveguide characteristics of a periodic 6-layer air-silica microstructure that maximises the power in the holes and evanescent power for biosensing applications is to have a as large as mechanically possible (i.e. large holes).","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

The authors review the guidelines for the design of modern optical communications systems, considering primarily the penalties and limitations posed by nonlinear effects in optical fibers. In WDM systems, nonlinear optical effects are traditionally divided into two categories. The first consists of intra-channel impairments where fiber nonlinearities interact with the transmitted waveform in a way that results in self imposed distortions, a mechanism known as self phase modulation. The second category consists of inter-channel effects, where the distortions experienced by one channel result from the propagation of other channels that are transmitted at other optical frequencies, mediated by fiber nonlinearities. The main nonlinear mechanisms that belong to this category are four-wave mixing, cross-phase modulation and stimulated Raman scattering.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

The method provides a variety of qualitative as well quantitative results for the soliton propagation. According to the variational method, the evolution of certain parameters of the pulse as its amplitude, duration and chirp can be obtained assuming a specific profile shape. This method provides all the major information about soliton oscillations and decay with propagation and it is in good agreement with numerical simulations of realistic systems.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

Adding insult to injury-molecular and functional perturbations of voltage-dependent calcium channel expression in disease 雪上加霜——疾病中电压依赖性钙通道表达的分子和功能扰动

{"title":"Adding insult to injury-molecular and functional perturbations of voltage-dependent calcium channel expression in disease","authors":"M. Mcenery","doi":"10.1109/LEOS.2001.969341","DOIUrl":"https://doi.org/10.1109/LEOS.2001.969341","url":null,"abstract":"VDCC (voltage-dependent calcium channels) play a central role as scaffolding proteins for the binding of synaptic vesicle and presynaptic membrane proteins. In addition to spatial constraints imposed by the localization of VDCC, the calcium that enters neurons via VDCC is exquisitely regulated kinetically leading to the formation of \"microdomains\" that extend from the mouth of the VDCC to a distance of approximately 50 nm in radius. Experimental access to this nanoscale domain has been limited. Recently, the importance of VDCC to normal neuronal function has been underscored by the identification of genetic lesions in specific VDCC subunits that lead to inherited forms of neuropathies in humans and mice. The primary defect is often coupled to downstream compensatory effects that result in the altered pattern of expression of non-mutated VDCC subunits. However, the connection between the molecular defects that arise within these microdomains as a consequence of mutated VDCC subunits and the ensuing neuropathy is not well established. We present recent biophotonic advances that afford experimental access and insight into this nanoscale microdomain. Furthermore we present novel molecular and biochemical probes that offer detailed analysis of the pattern of VDCC subunit expression and function in normal and diseased neurons. We anticipate that this high-resolution molecular analysis will delineate features that can serve as both diagnostic signatures of disease as well as potential therapeutic targets.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.
