This project aims to generate correlated photons directly on-chip from 2D materials.
The future quantum optical information processing (QOIP) field doesn’t have a “winning” platform yet. Once, of the approaches is to generate single photons on demand, identical (spectral purity) and in high quantity. One potential solution to this problem is to use nonlinear optical phenomena, such as spontaneous parametric down-conversion (SPDC), i.e. pumping the material at low optical wavelength (such as 750 nm) and observe the generation of correlated (produced at the same time and with correlated properties) photon pairs. These can then be entangled on-chip and used for modern QOIP. However, the ideal source of correlated photon pairs has to be demonstrated yet. Here we want to detect the SPDC from a 2D material deposited on a Si integrated waveguide. In this way we hope to increase the light-matter interaction and enhance the production of correlated photon-pairs which will be already couple into the waveguide and ready to be entangled and used directly on-chip. The project will first entails a linear and nonlinear characterization of the samples which are produced at ANU.
Additional supervisors for this research are Professor Dragomir Neshev from ANU and Dr Alexander Solntsev from UTS.
