Upconversion Dual-comb Passive Spectroscopy of Mid-IR Incoherent Light
Mingchen Liu, Matthew Heyrich, Sichong Ma +1
We introduce cross-comb correlation spectroscopy, which correlates signals from asynchronous sum-frequency sampling of mid-IR incoherent light with two near-IR combs. We experiment…
Optical-parametric-amplification-enhanced background-free spectroscopy
Mingchen Liu, Robert M. Gray, Arkadev Roy +2
Traditional absorption spectroscopy has fundamental difficulty in resolving small absorbance from strong background due to the instability of laser sources. Existing background-fre…
Mode-locked laser in nanophotonic lithium niobate
Qiushi Guo, Ryoto Sekine, James A. Williams +8
Mode-locked lasers (MLLs) have enabled ultrafast sciences and technologies by generating ultrashort pulses with peak powers substantially exceeding their average powers. Recently,…
Quadratic-soliton-enhanced mid-IR molecular sensing
Robert M. Gray, Mingchen Liu, Selina Zhou +3
Optical solitons have long been of interest both from a fundamental perspective and because of their application potential. Both cubic (Kerr) and quadratic nonlinearities can lead…
Visible-to-mid-IR tunable frequency comb in nanophotonics
Arkadev Roy, Luis Ledezma, Luis Costa +6
Optical frequency comb is an enabling technology for a multitude of applications from metrology to ranging and communications. The tremendous progress in sources of optical frequen…
High-Power Mid-IR Few-Cycle Frequency Comb from Quadratic Solitons in an Optical Parametric Oscillator
Mingchen Liu, Robert M. Gray, Arkadev Roy +5
Powerful and efficient optical frequency combs in the mid-infrared (MIR) spectral region are highly desirable for a broad range of applications. Despite extensive efforts utilizing…
Mid-Infrared Cross-Comb Spectroscopy
Mingchen Liu, Robert M. Gray, Luis Costa +3
Dual-comb spectroscopy has been proven a powerful tool in molecular characterization, which remains challenging to implement in the mid-infrared region due to difficulties in the r…
