  • Patent number: 10816792
    Abstract: Wavelength division multiplexing (WDM) has enabled telecommunication service providers to fully exploit the transmission capacity of optical fibers. State of the art systems in long-haul networks now have aggregated capacities of terabits per second. Moreover, by providing multiple independent multi-gigabit channels, WDM technologies offer service providers with a straight forward way to build networks and expand networks to support multiple clients with different requirements. In order to reduce costs, enhance network flexibility, reduce spares, and provide re-configurability many service providers have migrated away from fixed wavelength transmitters, receivers, and transceivers, to wavelength tunable transmitters, receivers, and transceivers as well as wavelength dependent add-drop multiplexer, space switches etc.

  • Patent number: 10615440
    Abstract: A power cell and a method for fabricating a power cell including two body portions and a proton exchange membrane (PEM) there between. The body portions each include a reaction chamber for holding an anolyte solution including a photosynthetic organism or a catholyte solution. At least one body portion has an optically transparent window to allow light into the reaction chamber enabling a photosynthetic reaction. A thin metal layer is coated directly on each of first and second surfaces of the PEM and then the two body portions are coupled together with the PEM located there between. Coating the first thin metal layer on the surfaces of the PEM involves coating a thin gold layer onto the surface, covering the gold layer with a layer of photoresist, patterning the photoresist layer through a mask, exposing the photoresist layer to ultraviolet radiation, and removing the unexposed photoresist.

  • Publication number: 20200001533
    Abstract: Additive manufacturing (AM) exploits materials added layer by layer to form consecutive cross sections of desired shape. However, prior art AM suffers drawbacks in employable materials and final piece-part quality. Embodiments of the invention introduce two new classes of methods, solidification and trapping, to create complex and functional structures of macro/micro and nano sizes using configurable fields irrespective of whether they need a medium or not for transmission. Selective Spatial Solidification forms the piece-part directly within the selected build material whilst Selective Spatial Trapping injects the build material into the chamber and selectively directs it to accretion points in a continuous manner. In each a localized spatiotemporal concentrated field is established by configuring or maneuvering field emitters. These methods are suitable to create any 3D part with high mechanical properties and complex geometries.

  • Patent number: 10345234
    Abstract: In order to implement a microfluidics sensor having higher efficiency, Applicants have developed a method of formation of nano-structures having various shapes and sizes onto materials such as polymers, glass and silicon, which are compatible with the microfabrication processes. The adhesion of the nano-structures and feasibility to tune their properties (optical, electrical and mechanical) are two prime concerns when they are adopted for microfluidics devices.

  • Publication number: 20140255730
    Abstract: Energy is probably one of the most important issues of the current century. New sources, approaches and systems have been studied in order to find suitable and more reliable power sources and energy harvesting devices. In addition, mobile Micro Electro Mechanical Systems (MEMS) devices require micro power sources as well. So far, there has been vast research and investment on solar sources, fuel cells, etc. The present application is an attempt to develop a suitable fabrication method to realize a Photosynthetic Power Cell (?PSO) to harvest the energy from photosynthesis and produce electrical energy. The proposed ?PSO is a micro power generation device made from polymer material for generating power from algal photosynthesis. In particular, the present application presents a fabrication process for realising a ?PSO from polymer material.
