Photonic chip-based low noise microwave oscillator
Igor Kudelin, William Groman, Qing-Xin Ji +26
Numerous modern technologies are reliant on the low-phase noise and exquisite timing stability of microwave signals. Substantial progress has been made in the field of microwave ph…
Broadband coherent Raman scattering spectroscopy at 50,000,000 spectra/s
Takuma Nakamura, Kazuki Hashimoto, Takuro Ideguchi
Raman scattering spectroscopy is widely used as an analytical technique in various fields, but its measurement process tends to be slow due to the low scattering cross-section. In…
Upconversion time-stretch infrared spectroscopy
Kazuki Hashimoto, Takuma Nakamura, Takahiro Kageyama +4
High-speed measurement confronts the extreme speed limit when the signal becomes comparable to the noise level. In the context of broadband mid-infrared spectroscopy, state-of-the-…
A simple approach of broadband mid-infrared pulse generation with a mode-locked Yb-doped fiber laser
Takuma Nakamura, Venkata Ramaiah Badarla, Kazuki Hashimoto +2
Broadband mid-infrared (MIR) molecular spectroscopy demands a bright and broadband light source in the molecular fingerprint region. To this end, intra-pulse difference frequency g…
Coherent Optical Clock Down-Conversion for Microwave Frequencies with 10-18 Instability
Takuma Nakamura, Josue Davila-Rodriguez, Holly Leopardi +12
Optical atomic clocks are poised to redefine the SI second, thanks to stability and accuracy more than one hundred times better than the current microwave atomic clock standard. Ho…
