We report on the realization of high-quality organic microcavities consisting of distributed Bragg reflectors based on lithium fluoride (LiF) and tellurium dioxide (TeO[sub x]) deposited by thermal evaporation. The materials are transparent in the range of 350 nm–5 μm and have an evaporation temperature of about 1000 K. The large difference in the refractive index (about 0.9 in the visible and near-infrared range) allows one to obtain reflectivity higher than 99% over a spectral region about 200 nm wide with a small number of periods. The mirror deposition technique is suitable for the fabrication of organic quantum microcavities in a single deposition process. Three fully evaporated organic λ cavities with Phyrrometene 580 as the active material are described. The cavities show a Q value of up to 300, good uniformity, and reproducibility. © 2001 American Institute of Physics.

    We have designed [sup 4]He cryostats which can be inserted into storage Dewars. These cryostats have the advantages of extremely low (and recoverable) helium consumption, fast cool-down and warm-up times, excellent temperature range and stability, and they supply a low electrical noise and low...

    A special calorimeter is described which is capable of detecting molecular hydrogen trapped in solid material. It takes advantage of the energy released by the slow ortho-para conversion of H[sub 2] after rapid cooling from room temperature to 4.2 K. The technique is simple, quantitative, and...

    The brittleness of the polycrystal silicon ribbons is due to the residual stresses which appear in the material during the electron-powder-ribbon pulling process. We developed a new method for stress analysis based on combination of two techniques: classical infrared photoelasticity and modern...
