Comparing the Linewidths from Single-Pass SPDC and Singly-Resonant Cavity SPDC

September 3, 2015
Author(s)
Oliver T. Slattery, Lijun Ma, Paulina S. Kuo, Xiao Tang
Spontaneous parametric down-conversion (SPDC) is a common method to generate entangled photon pairs for use in quantum communications. The generated single photon linewidth is a critical issue for photon-atom interactions in quantum memory applications. We

EIT Quantum Memory with Cs Atomic Vapor for Quantum Communication

September 1, 2015

Lijun Ma, Oliver T. Slattery, Paulina S. Kuo, Xiao Tang
Quantum memory is a key device in the implementation of quantum repeaters for quantum communications and quantum networks. We demonstrated a quantum memory based on electromagnetically-induced transparency (EIT) in a warm cesium atomic cell. The quantum

Entangled photon generation in a phase-modulated, quasi-phasematched crystal

October 14, 2013

Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Yong-Su Kim, Xiao Tang
We propose a scheme to generate polarization-entangled photon pairs by spontaneous parametric downconversion in a phase-modulated, type-II, quasi-phasematched (QPM) crystal. Instead of using two distinct crystals to generate |HV>and |VH> states, the phase

Spectral response of an upconversion detector and spectrometer

September 17, 2013
Author(s)
Paulina S. Kuo, Oliver T. Slattery, Yong-Su Kim, Jason S. Pelc, M. M. Fejer, Xiao Tang
We theoretically and experimentally investigate the spectral response of an upconversion detector and discuss implications for its use as an infrared spectrometer. Upconversion detection is based on high-conversion-efficiency sum-frequency generation (SFG)

Two-photon interference with continuous-wave operating multi-mode coherent light

September 12, 2013
Author(s)
Yong-Su Kim, Oliver T. Slattery, Paulina Kuo, Xiao Tang
We report two-photon interference with continuous-wave multi-mode coherent light. We show that the two-photon interference, in terms of the detection time difference, reveals two-photon beating fringes with the visibility V = 0.5. While scanning the

Conditions for two-photon interference with coherent pulses

July 1, 2013
Author(s)
Yong-Su Kim, Oliver T. Slattery, Paulina Kuo, Xiao Tang
We report experiments on two-photon interference between temporally non-overlapping weak coherent pulses. While the single-photon interference is washed out, the two-photon interference shows a Hong-Ou-Mandel dip with visibility of 0.50±0.09, which shows
