Ultralow Loss, High Q, Four Port Resonant Couplers for Quantum Optics and Photonics [PDF]
, 2004 We demonstrate a low-loss, optical four port resonant coupler (add-drop geometry), using ultrahigh Q (>108) toroidal microcavities. Different regimes of operation are investigated by variation of coupling between resonator and fiber taper waveguides.
