Bidirectional Pumping for Entangled Photons
Abhishek Anchal, Pradeep Kumar Krishnamurthy · Advanced Photonics Congress · 2012
We propose a bidirectional pumping scheme to increase the efficiency of entangled photon pair generation at telecom wavelengths. Simulation results with 25ps/40 MHz Gaussian pulses show 26% increase in signal power and 33% decrease in pump power required to generate same signal power as in the unidirectional pumping.
