Development of Novel Instrument for Easy Measurement of Refractive Index of High-temperature Molten Materials

October 21, 2011 · Filed Under Trendy Products · Comments Off on Development of Novel Instrument for Easy Measurement of Refractive Index of High-temperature Molten Materials 

High temperature molten states are basically liquid states which occur during refining process of the material as well as optical disk writing and reading processes. The high temperature melting process is essential for refining material, and in particular it is used in rewritable optical disk field, where the process of melting the materials making up the thin film on the disk through the irradiation of laser light and rapidly cooling them which is essential during writing or reading disk. Based on this evaluation of materials at very high temperature is essential for efficient control of process and products structural design. The most important evaluation method so far is evaluation of the refractive index of material which is essential for the calibration of the radiation thermometers which is used in refining process as well for determining how well an optical disk responds to laser light. However, it is very difficult to measure the refractive index of a molten material at a high temperature for various reasons including the fact that high temperature makes it impossible to touch the material during measurement adjustment, not to mention the high temperatures cause the materials to evaporate or react with its surrounding air. Due to this difficulty up to now, these sort of measurements have been conducted under extremely limited conditions with a supervision of highly trained individual with experience in using highly specialized instruments. Based on this, group of researchers at AIST have developed a instrument which is capable of measuring refractive index of molten materials at a very high temperature. Read more

Achieving High-Speed Optical Communication based on New “Quantum Receiver” Technology

July 27, 2011 · Filed Under Trendy Products · 1 Comment 

Performance of optical communications is determined by its bit error rate otherwise known as BER, in discriminating the signals “0” and “1”, which consequently can be lowered by eliminating noises in the system. By elimination of these noises face a certain boundary which is known as quantum noise. At the same time the BER can be lowered to a certain limit which is called “the short noise limit”, or SNL. In theory at least a BER can be reduced below the SNL level through simple controlling of quantum noise. However, controlling quantum noise in an optical receiver has sought to be a formidable task. To face this challenge group of researchers at NICT has developed a new quantum receiver which is capable of suppressing the effect of quantum noise through introduction of new technology which controls the particle nature of light (photons), to conventional optical communication which controls the wave characteristic of light.
