Abstract

Recent advances in the production of high-purity synthetic diamonds have made diamond an accessible host material for applications in present and future optoelectronic and photonic devices. We have developed a scalable process for fabricating photonic devices in diamond using reactive ion etching (RIE) and photolithography as well as using ion implantation to provide vertical confinement. Applying this we have demonstrated a few-moded waveguide with a large cross section for easier coupling to optical fibre. We present our work towards in-plane coupling to diamond waveguides and consequently characterisation of these waveguides. We also examine the application of diamond waveguides to other photonic applications for achieving light confinement in a subwavelength cavity site using a slot-waveguide design. Such cavities may be used to enhance photon-emission properties of a built-in diamond colour centre and to achieve strong light-matter interactions on the single-quantum level necessary for quantum information technology. Using single cavities as building block, we also show that these structures can be suitably coupled to form one-dimensional coupled-resonator array.
