Deep-ultraviolet light source by frequency doubling of blue or green light for disinfection. Current ultraviolet light sources are inefficient and often bulky. By an alternative approach, in which the wavelength of blue or green light is halved, this project will design and build compact, efficient sources of ultraviolet light, which can be used for disinfection and sterilization. Such devices can be fabricated by Australian industry in Australia.

Hybrid plasmonic waveguide for integrated photonic signal processing. Fast processing of information is central to modern society. This task is traditionally carried out by electronics, which however is becoming too slow and energy-consuming for some tasks.

Fast processing of information is central to modern society. This task is traditionally carried out by electronics, which however is becoming too slow and energy-consuming for some tasks. Among alternative technologies optics is the most promising, because it is fast and potentially energy efficient, but possible optical solutions are either quite bulky or suffer from high ohmic losses because the light needs to travel through metal. This project aims to design and fabricate a device which emits a train of short pulses, a key requirement for any signal processing, and in which the light resides mostly in low-loss material. By using metals merely to confine the light, such a 'hybrid' device would avoid the drawbacks of traditional photonic solutions.Read moreRead less
