Compact all-solid-state source of polarization-entangled photon pairs
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. {copyright} 2001 American Institute of Physics.
