Fast path and polarisation manipulation of telecom wavelength single photons in lithium niobate waveguide devices [PDF]

, 2011
We demonstrate fast polarisation and path control of photons at 1550 nm in lithium niobate waveguide devices using the electro-optic effect. We show heralded single photon state engineering, quantum interference, fast state preparation of two entangled ...
