Multi-Channel Fiber-Based Source of Polarization Entangled Photons with Integrated Alignment Signal
Shawn X. Wang, Gregory S. Kanter, Prem Kumar · 2009
We describe a fiber source of polarization entangled photons entirely constructed with fiber-coupled commercial components. A built-in alignment signal allows systematic setting of downstream measurement basis. Entanglement is measured at several signal-idler channels simultaneously.
