Electrical and Optical Manipulation of Polariton Condensates on a Chip

Following the observation of Bose Einstein condensation of cavity exciton-polaritons attention has shifted towards realization of polariton based devices. I will review recent progress on realization of practical polariton based…

Engineering coherent artificial atoms

Strong quantum confinement has led to the observation of discrete, atom-like energy levels in solid-state quantum dots (QDs). However, for a typical self-assembled QD the confinement potential of a particle…

Optoelectronics with 2D semiconductors

Two-dimensional (2D) atomic crystals, such as graphene and layered transition-metal dichalcogenides, are currently receiving a lot of attention for applications in (opto-)electronics. In this talk I will review our research…

Multiplexing heralded photons: sources and applications

In this talk I will discuss the use of different multiplexing techniques on photons generated by spontaneous four wave mixing in slow-light silicon photonic crystal waveguides.  The first experiment uses…
