Reducing the size and weight of electrical / electronic equipment often gives rise to parasitic effects such as ringing and resonance, which are particularly disrupting to high-frequency circuits or systems. To address that problem, CityU researchers have developed a device capable of improving the .....

This invention can cancel undesirable noise generated by the components’ parasitic inductances, physical orientation, and the layout of conductive tracks on the printed circuit boards. It can effectively improve the high-frequency response of the entire circuit or system. The invented method can be.....

This invention presents light maximization method for LED systems. Derived from a general theory that links the photometric, electric and thermal behaviours of LED systems together, the method provides the rules to design LED systems with maximum light output. Its main contribution is to provide cle.....

Success in erbium doped fiber amplifier (EDFA) research has stimulated the development of Er doped glass planar waveguide devices. Planar waveguide components, allowing integration with other optoelectronic devices on the same chip and efficient waveguide-to-fiber coupling, are very attractive for .....

The invention relates to fast processing techniques designed for enhancing the pictorial contents of digital holograms, without the need to reconstruct the original 3D scene. The hologram is back-projected to a hypothetical 2D image known as virtual diffraction plane (VDP). The VDP is then processed.....
