It is believed that these elements have the potential to produce a highly secure, anti counterfeiting optical watermark. University Technology Fri, 12 Jun 2009 10:04:29 +0100 http://unitech.dogdigital.net/details/polymer-technology-for-emerging-high-growth-markets Ultraviolet light has many existing uses and markets currently using a variety of light sources including mercury vapour lamps and lasers. With major recent progress in ultraviolet LEDs (Light Emitting Diodes) helping to extend markets, the introduction of this family of polymers is timely. Existing polymer materials do not transmit ultraviolet light below 300nm in wavelength. There are many application and markets to which polymers transmitting light below 300nm will be valuable. University Technology Tue, 14 Apr 2009 13:52:14 +0100 http://unitech.dogdigital.net/details/silicon-carbide-bonding---high-integrity-structural-joining-of-parts A method for bonding at least two parts, at least one part comprising silicon carbide. The method comprises forming a layer of silica on the silicon carbide surface and applying to it a bonding solution that includes hydroxide ions. Once this is done, the part that is to be bonded to the silicon carbide is moved into contact with the solution coated silica surface on the carbide. The method can be used to bond silicon carbide to itself or to components made of other selected materials.

Ongoing development in the COSMIC laboratory has demonstrated applications in single cell and molecule studies. Many potential applications exist in the physical and life-science fields. University Technology Mon, 04 Sep 2006 16:16:45 +0100 http://unitech.dogdigital.net/details/optical-dental-diagnosis With recent discoveries in the way that dental disease develops, the desire for the dentist to be able to detect, and subsequently diagnose, early caries has increased significantly. By adapting technology originally developed for the telecommunications industry the Institute of Photonics has built a confocal microscope suitable for use in the oral cavity. By utilising low cost laser diodes and optical fibres the instrument is capable of recording depth profiles through a lesion. The resulting curves can then be analysed and the depth and state of de-mineralisation within the lesion determined.

This technology relates to gallium nitride (GaN) semiconductor devices which are most familiar as high brightness blue and green LEDs. The new technology is an aluminium indium gallium nitride layer which provides a means to optically monitor, in situ, the growth of GaN devices on newly developed GaN substrates. University Technology Mon, 14 Nov 2005 11:35:28 +0100 http://unitech.dogdigital.net/details/vecsel-semiconductor-lasers Compound semiconductors form the basis of modern optoelectronics technology, enabling specialised devices, such as semiconductor lasers, for applications in areas as diverse as optical data storage, telecommunications, and displays. VECSELs, a category of semiconductor laser, are becoming more and more popular because they offer wavelength flexibility from UV to near infra-red and Watt-level output in high-quality beams. However, existing VECSELs are cumbersome, expensive and of limited performance. University Technology Wed, 09 Nov 2005 10:26:31 +0100 http://unitech.dogdigital.net/details/high-frequency-radiofrequency-pulse-generator HIGH FREQUENCY RADIOFREQUENCY PULSE GENERATOR The new methodology employs types of multipliers as switches. Such devices may be found with intrinsic bandwidths of many Gigahertz and because they are designed to be high frequency components have very small internal capacitances. The non-linearity inherent in the multiplication process will “speed up” the pulse edges giving additional pulse width compression. This technique, carried out at low frequencies, also means that switch losses may be compensated at frequencies at which gain is relatively cheap.
