- The work reported a high-sensitivity visible light detector with an inherent narrow optical response, by utilising the material of AlInP, for underwater optical communication links. The narrow optical response eliminates external optical filters and their disadvantages (reliability and varying optical attenuation performance). The design was implemented through epitaxial wafer growth, device fabrication and device characterisation, which covered electrical and optical characteristics of at least three devices. The main result (spectral responses) exceeded data from commercial photodiode and another AlInP detector without the high-sensitivity feature. The results led to a commercial project on AlInP avalanche photodiodes (contact: Lead Technologist-Sensing, BAE Systems).
