Waveguide-based single-pixel up-conversion infrared spectrometer
Qiang Zhang, Carsten Langrock, M. M. Fejer +1
A periodically poled lithium niobate (PPLN) waveguide-based single-pixel up-conversion infrared spectrometer was demonstrated. Sum-frequency generation between a 1.5 micrometer ban…
Signature of the microcavity exciton-polariton relaxation mechanism in the polarization of emitted light
Georgios Roumpos, Chih-Wei Lai, T. C. H. Liew +3
We have performed real and momentum space spin-dependent spectroscopy of spontaneously formed exciton polariton condensates for a non-resonant pumping scheme. Under linearly polari…
Unconditional Security of Single-Photon Differential Phase Shift Quantum Key Distribution
Kai Wen, Kiyoshi Tamaki, Yoshihisa Yamamoto
In this Letter, we prove the unconditional security of single-photon differential phase shift quantum key distribution (DPS-QKD) protocol, based on the conversion to an equivalent…
