| dc.description.abstract | Experiments on entangled photon pairs and astronomical interference require an ultrafast shutter that can isolate desired photon pulses. The Kerr-effect in third order nonlinear optics has been used to create a shutter that operates on the femtosecond timescale. Low noise Kerr-effect shutters capable of completing single photon pair experiments have been created using high pump filtering and high signal transmission.1,2 Unlike other low noise shutters, measurements of Raman scattering from the pump pulses are collected. Another unique feature of this Kerr-Effect shutter is that it uses signal and pump wavelengths, 1550nm and 850nm, respectively, that have not been tested in previous research. Unfortunately, the Raman scattering measurements must be retaken due to potential errors with the pump beam being continuous wavelength instead of pulsed. Transmitted signal power was measured in relation to pump power and pump polarization angle, both of which indicated the possible presence of the Keff effect. Our Kerr shutter managed to isolate 31.9% of the expected power. | en_US |
