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

October 14, 2013
Author(s)
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

Efficient, low-noise, single-photon frequency conversion

June 9, 2013
Author(s)
Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Yong-Su Kim, M. M. Fejer, Xiao Tang
We demonstrate simultaneous low-noise and efficient frequency conversion in a periodically poled LiNbO3 waveguide with spectral filtering. We achieve >50% external conversion efficiency and 600 noise counts per second at peak conversion.

Frequency Correlated Bi-Photon Spectroscopy using a Tunable Up-Conversion Detector

May 21, 2013
Author(s)
Oliver T. Slattery, Lijun Ma, Paulina S. Kuo, Yong-Su Kim, Xiao Tang
We demonstrated a scheme for frequency correlated bi-photon spectroscopy using a strongly non- degenerate down-conversion source and a tunable up-conversion detector. In this scheme, the spectral function at one wavelength range of a remote object can be

April 10, 2013
Author(s)
Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Yong-Su Kim, Martin M. Fejer, Xiao Tang
We demonstrate low-noise and efficient frequency conversion using sum-frequency mixing in a periodically poled LiNbO3 (PPLN) waveguide. Using a 1556 nm pump, 1302 nm photons are efficiently converted to 709 nm photons. We obtain 70% conversion efficiency

Dual-channel, single-photon upconversion detector near 1300 nm

November 5, 2012
Author(s)
Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Martin M. Fejer, Xiao Tang
Upconversion of 1.3-micron photons and detection using silicon avalanche photodiodes (Si APDs) can produce high photon detection efficiencies (PDEs) with low dark count rates. We demonstrate a novel two-channel device based on a phase-modulated

Photon Temporal Correlations Measured Using a Dual-Channel Upconversion Detector

October 14, 2012
Author(s)
Paulina Kuo, Jason S. Pelc, Oliver T. Slattery, Martin M. Fejer, Xiao Tang
We demonstrate application of a dual-channel upconversion detector as a beamsplitter that preserves photon statistics. We use this beamsplitter to characterize temporal correlations of photons from coherent and pseudo-thermal sources.

Dual-channel, single-photon upconversion detector at 1.3 mm

August 3, 2012
Author(s)
Jason S. Pelc, Paulina Kuo, Oliver T. Slattery, Lijun Ma, Xiao Tang, Martin M. Fejer
We demonstrate efficient, single-photon upconversion detection of two wavelengths in the 1300-nm band. The upconversion detector is based on a phase-modulated, periodically poled LiNbO3 waveguide that simultaneously quasi-phasematches two sum-frequency

Dual-channel, single-photon upconversion detector at 1300 nm

August 3, 2012
Author(s)
Paulina Kuo, Jason S. Pelc, Oliver T. Slattery, Lijun Ma, Martin M. Fejer, Xiao Tang
We show a dual-channel, upconversion detector at 1.3-m-wavelength based on phasemodulated periodically poled LiNbO3, and use it for wavelength- to time-division multiplexing to achieve high data rates, useful for quantum key distribution.

4-bar-quasi-phasematching for second-harmonic generation in microdisks

August 15, 2011
Author(s)
Paulina S. Kuo, Glenn S. Solomon
We present a theoretical description of resonantly enhanced, 4-bar-quasi-phasematched, second-harmonic generation in microdisks made of materials possessing 4-bar symmetry, such as GaAs, GaP and ZnSe. The theory describes the interplay between quasi

Quasi-phasematched Second Harmonic Generation in GaAs Microdisks

November 15, 2009
Author(s)
Paulina S. Kuo, W Fang, Glenn S. Solomon
We discuss design and tuning of second-harmonic generation in GaAs microdisks. Quasi-phasematching can be achieved in the microdisk geometry without external domain inversions, but efficient nonlinear optical mixing requires that all waves be resonant
