Nano-photonic circuits with integrated quantum emitter — •Philip Schrinner, Marius Otte, Rene Henke, and Carsten Schuck — Physikalisches Institut and Center for Nanotechnology, WWU Münster, Germany

Realizing quantum information processing technologies on a scalable platform are expected to have a disruptive impact on cryptography, communication and computing. Advanced CMOS fabrication is a promising tool for integrating large-scale quantum photonic circuits on silicon. We consider such a system, where single photons are manipulated in nano-photonic waveguide devices. The implementation consists of single photon sources (SPS), nano-photonic circuits and single photon detectors. In this work we aim on coupling nano-scale quantum emitters with waveguide devices to supply single-photons into photonic integrated circuits. We present techniques to deterministically place the nano emitters in the evanescent field of an optical waveguide, where nitrogen vacancy centers in nano diamonds serve as an example. Additionally, suitable nano-photonic devices for the integration of nano emitters are rapidly prototyped by employing nano-fabrication routines and automated fiber-optic measurement capabilities. The spectral and statistical properties of quantum emitters are at first investigated in confocal microscopy. After the positioning process the coupling between the quantum emitter and an optical waveguide is investigated. Integration of single-photon sources with SNSPDs linked via nanophotonic circuits on a silicon chip will then constitute a key step towards scalable quantum information processing.
