Optical and Raman spectroscopies of 171Yb3+:Y2SiO5 hyperfine structure for application toward microwave-to-optical transducer
Hee-Jin Lim, Ga-Hyun Choi, Ki Suk Hong
This study analyzed the optical techniques for high resolution, low-noise spectroscopy of a hyperfine structure (HFS) made of ytterbium-isotope 171 ions (:$…
Characterization of single photon sources for radiometry applications at room temperature
Hee-Jin Lim, Dong-Hoon Lee, In-ho Bae +5
A single photon source with high repeatability and low uncertainties is the key element for few-photon metrology based on photon numbers. While low photon number fluctuations and h…
Modular system for fluorescence-based single photon generation using retro-reflector
Hee-Jin Lim, Kwang-Yong Jeong, Dong-Hoon Lee +1
Apparatus for fluorescence-based single photon generation includes collection optics and various setups for characterization. Managing this system often reveals complexity in such…
Silicon photonic crystal cavities at near band-edge wavelengths
Salahuddin Nur, Hee-Jin Lim, Jeroen Elzerman +1
We demonstrate photonic crystal L3 cavities with resonant wavelength around 1.078 \textmu m on undoped silicon-on-insulator, designed to enhance spontaneous emission from phosphoru…
Coherent spin dynamics of ytterbium ions in yttrium orthosilicate
Hee-Jin Lim, Sacha Welinski, Alban Ferrier +2
We investigate the electron and nuclear spin coherence properties of ytterbium () ions with non-zero nuclear spin, within an yttrium orthosilicate (YSiO)…
