Integrated Optics for Computing and Sensing

Integrated photonics, already important for classical communication, has numerous other potential applications that are being explored. This talk will describe several research projects in the Large-Scale Integrated Photonics Group at HP Labs related to quantum computing, classical computing, and sensing.

First, I will describe our attempts to develop components of an on-chip optical network in diamond to enable generation of entangled states between nitrogen-vacancy (NV) spin qubits. While the difficulties of fabricating useful devices in diamond are formidable, we have demonstrated several types of resonators that can enhance spontaneous emission rates and photon collection efficiencies from NV centers, as needed to increase the success rate in schemes for entanglement formation. 

Next, I will describe a new project in which we are studying all-optical switching in coherent, nonlinear optical networks on a semiconductor platform. I will mainly focus on semi-classical simulations of the effects of quantum noise in large-scale circuits containing hundreds of components.

Finally, as time permits I will show some very recent results related to imaging, sensing and displays.
