Photodiodes

Natural photodetection and light imaging systems are able to undertake a myriad of functions including high spatial and spectral resolution, far field imaging, ultra violet (UV) and infrared red (IR) vision. At COPE we have been developing strategies for developing photodiodes that are capable of identifying the true colour of objects independent of the light source. Through a combination of light absorbing materials development and device electro-optics, COPE has been able to realise photo-responses will full-width-half-maxima of less than the critical 100 nm. Such photodiodes could be used to help autonomous systems see through machine vision as well as improving our everyday cameras.
