Towards all-diamond optical devices

Diamond is a unique material, with a host of attributes that seem to favour is as a platform for solid-state optical approaches to quantum information processing. Amongst the many outstanding properties of diamond, the most important for these applications are that it posses the largest transparency window in the visible regime, has the highest thermal conductivity, and most importantly, hosts a large number of high dipole moment colour centres. In this paper we give an overview of the fabrication and characterisation of diamond-based optical devices at the University of Melbourne.
