We demonstrate a low-cost, fiber-based, pulsed entanglement source, using periodically-poled silica fiber and a pulsed 780nm diode laser, which generates ~1ns pulses of polarization-entangled photon pairs at up to 60MHz, 0.15 pairs/pulse.

Compact all-solid-state source of polarization-entangled photon pairs

Jürgen Volz, Christian Kurtsiefer, Harald Weinfurter

A compact source of polarization-entangled photon pairs at a wavelength of 856 nm is realized using a frequency-doubled laser diode as the pump source for cavity-enhanced type-II spontaneous parametric down-conversion. Our setup generates photon pairs with entanglement visibility of ⩾95% and with count rates comparable to those of standard experiments based on large-frame ion lasers.

Collinear source of polarization-entangled photon pairs at nondegenerate wavelengths

Pavel Trojek, Harald Weinfurter

We report on a simple but highly efficient source of polarization-entangled photon pairs at nondegenerate wavelengths. The fully collinear configuration of the source enables very high coupling efficiency into a single optical mode and allows the use of long nonlinear crystals. With optimized dispersion compensation, it is possible to use a free-running laser diode as pump source and to reach an entanglement fidelity of 99.4% at rates as high as 27000pairs∕s∕mW of pump power.
