Micromachined silicon grisms for infrared optics.
We demonstrate the successful fabrication of large format (approximately 50 mm × 50 mm) gratings in monolithic silicon for use as high-efficiency grisms at infrared wavelengths. The substrates for the grisms were thick (8-16 mm) disks of precisely oriented single-crystal silicon (refractive index, n ~ 3.42). We used microlithography and chemical wet etching techniques to produce the diffraction...
متن کاملFOCAS: An Enginering Environment for Service-Based Applications
Service composition is an important topic, but so far addressed from a technical and low level perspective. The issue is not (too much) the orchestration formalism, but rather the engineering issues related to the many concerns that must be combined, to the technical complexity, to the heterogeneity and incompatibilities between available services, and the low level formalism and tools. The pap...
متن کاملEvaluation of Selection Criteria for WFC3 Replacement IR Grisms
This report describes the rationale for recommending focus as the primary selection criterion in choosing the final IR replacement grisms. Introduction Instrument-level imaging during the first thermal vacuum ground test of the WFC3 IR channel in the fall of 2004 revealed that while the IR filters performed as expected, well within specification, the grisms produced significantly out-of-focus, ...
متن کاملDistributed Orchestration Versus Choreography: The FOCAS Approach
Web service orchestration is popular because the application logic is defined from a central and unique point of view, but it suffers from scalability issues. In choreography, the application is expressed as a direct communication between services without any central actor, making it scalable but also difficult to specify and implement. In this paper we present FOCAS, in which the application i...
متن کاملEfficient reflection grisms for pulse compression and dispersion compensation of femtosecond pulses.
Efficient reflection grisms for pulse-compression and material-dispersion compensation have been designed and demonstrated in a 40 fs, 300 microJ, 5 kHz downchirped pulse amplification system for the first time to our knowledge. A grism design for 800 nm femtosecond laser pulse dispersion compensation applications is realized by using standard, commercial diffraction gratings.
