Modeling of As2S3 raman fiber lasers operating in the mid-infrared

A numerical study of As2S3 Raman fiber lasers is carried out to show their potential for the entire coverage of the 3–4-m spectral band. Experimental results are first obtained from such a laser operated under controlled conditions in order to set the fiber parameters (i.e., gain and attenuation coefficients) to be used in the numerical model. An exhaustive numerical analysis is then performed to establish the conditions for optimum lasing performances over the entire 3–4-m spectral band.

Tailoring the refractive index of Ge-S based glass for 3D embedded waveguides operating in the mid-IR region

The photosensitivity of GeSx binary glasses in response to irradiation to femtosecond pulses at 800 nm is investigated. Samples with three different molecular compositions were irradiated under different exposure conditions. The material response to laser exposure was characterized by both refractometry and micro-Raman spectroscopy. It is shown that the relative content of sulfur in the glass matrix influences the photo-induced refractive index modification. At low sulfur content, both positive and negative index changes can be obtained while at high sulfur content, only a positive index change can be reached. These changes were correlated with variations in the Raman response of exposed glass which were interpreted in terms of structural modifications of the glass network. Under optimized exposure conditions, waveguides with positive index changes of up to 7.8x10−3 and a controllable diameter from 14 to 25 μm can be obtained. Direct inscription of low insertion losses (IL = 3.1 – 3.9 dB) waveguides is demonstrated in a sample characterized by a S/Ge ratio of 4. The current results open a pathway towards the use of Ge-S binary glasses for the fabrication of integrated mid-infrared photonic components.

O impacto da adesão aos diferentes níveis de Governança Corporativa para o desempenho econômico e financeiro de um segmento de empresas

The importance of the capital market to Brazilian economic development, linked to the the fragility of a theoretical framework on the issue, case for developing this research. The agents operating in the capital market seek security and confidence for decision making on their investment in that sense we seek to address the concept and values of Corporate Governance to pay in the Brazilian capital market. The Corporate Governance, in its essence, is the system by which companies are directed and monitored, involving the relationship between shareholders and the board of companies, as well as a set of mechanisms and factors intended to minimize market failures. Seeking to confirm adherence to a more advanced system of corporate governance can result in a favorable financial performance, companies were investigated operating in the financial sector (intermediation, various services and insurance), listed by BM&FBOVESPA. The stock market ranks the corporate governance systems in three levels: Level 1 (rudimentary), Level 2 (intermediate) and New Market Level (advanced). To earn the impact of different levels of Corporate Governance for the outcome of the selected companies were calculated and analyzed accounting ratios of profitability, capital structure and liquidity from the Standardized Financial Statements (DFP), base year 2011, 2012 and 2013

Planejamento para a implantação da ISO 9001 em uma empresa do setor industrial

The fierce competitiveness of the current market and the sophistication of customer requirements made the commitment to quality a need within organizations. The search for quality has been carried out by the adoption of quality management systems, a formal organization that should be present throughout the organization, from the initial identification of market needs to the satisfaction of customer requirements. The methodology most commonly used for this purpose is based on the requirements of ISO 9001, latest version of 2008. Considering this scenario, was developed a case study in a small company of the industrial sector with the development of a plan for the implementation of ISO 9001. The proposed methodology involved the construction of a theoretical framework on the subject and the development of a case study with a qualitative approach. Initially, was applied a questionnaire to the representative of the organization about the company's operating procedures, activity logs held, current documentation, planning and resource management for the construction of an assessment about the adequacy of the company needs to ISO 9001. Were obtained as results the characterization of production processes and organizational structure of the company and examples of policy and objectives of quality, performance indicators, document control, system for visualization of non-compliances, among others. Finally, the benefits of adopting a quality management system based on ISO 9001 requirements for the company and its environmental issues such as increased process efficiency, less waste and greater profitability, were pointed out, and the conditions for effective certification in the future
