Plasmon-based waveguides for quantum photonics 

Plasmon-based waveguide configurations are considered and assessed from the perspective of their use for quantum plasmonics, paying attention to the fundamental trade-off between the mode confinement and the propagation loss incurred due to the light absorption in metals. Recent advances in deterministic positioning of individual quantum emitters (QDs or NV centers) near plasmonic structures and in realization of ultracompact plasmonic integrated circuits are also overviewed. Finally, fundamental limits in the achievable plasmonic mode confinement (and effective Purcell factors) due to electron tunneling and nonlocal-response effects are discussed.
