Direct generation of frequency-bin entangled photons via two-period quasi-phase-matched parametric downconversion
Fumihiro Kaneda, Hirofumi Suzuki, Ryosuke Shimizu +1
We report a simple scheme for direct generation of frequency-bin entangled photon pairs via spontaneous parametric downconversion. Our fabricated nonlinear optical crystal with two…
Theoretical investigation of a spectrally pure-state generation from isomorphs of KDP crystal at near-infrared and telecom wavelengths
Rui-Bo Jin, Neng Cai, Ying Huang +6
Spectrally uncorrelated biphoton state generated from the spontaneous nonlinear optical process is an important resource for quantum information. Currently such spectrally uncorrel…
Quantum manipulation of biphoton spectral distributions in a 2D frequency space toward arbitrary shaping of a biphoton wave packet
Rui-Bo Jin, Ryoji Shiina, Ryosuke Shimizu
In this work, we experimentally manipulate the spectrum and phase of a biphoton wave packet in a two-dimensional frequency space. The spectrum is shaped by adjusting the temperatur…
Experimental demonstration of time-frequency duality of biphotons
Rui-Bo Jin, Takuma Saito, Ryosuke Shimizu
Time-frequency duality, which enables control of optical waveforms by manipulating amplitudes and phases of electromagnetic fields, plays a pivotal role in a wide range of modern o…
