Radiative thermal diode via hyperbolic metamaterials
Qizhang Li, Haiyu He, Qun Chen +1
Hyperbolic metamaterials (HMMs) support propagating waves with arbitrarily large wavevectors over broad spectral ranges, and are uniquely valuable for engineering radiative thermal…
A quantum cascade laser-based mid-IR frequency metrology system with ultra-narrow linewidth and -level frequency instability
Michael G. Hansen, Evangelos Magoulakis, Qun-Feng Chen +2
We demonstrate a powerful tool for high-resolution mid-IR spectroscopy and frequency metrology with quantum cascade lasers (QCLs). We have implemented frequency stabilization of a…
A compact, robust, and transportable ultra-stable laser with a fractional frequency instability of
Qun-Feng Chen, Alexander Nevsky, Marco Cardace +5
We present a compact and robust transportable ultra-stable laser system with minimum fractional frequency instability of at integration times between 1 to 10 s. T…
Radiation Hardness of High-Q Silicon Nitride Microresonators for Space Compatible Integrated Optics
Victor Brasch, Qun-Feng Chen, Stephan Schiller +1
Integrated optics has distinct advantages for applications in space because it integrates many elements onto a monolithic, robust chip. As the development of different building blo…
Robust frequency stabilization of multiple spectroscopy lasers with large and tunable offset frequencies
Alexander Nevsky, Soroosh Alighanbari, Qun-Feng Chen +7
We demonstrate a compact and robust device for simultaneous absolute frequency stabilization of three diode lasers whose carrier frequencies can be chosen freely relative to the re…
Proton irradiation robustness of dielectric mirrors for high-finesse Fabry-Pérot resonators in the near-infrared spectral range
Qun-Feng Chen, Alexander Nevsky, Stephan Schiller +3
We demonstrate that a proton irradiation with fluences of /cm at low energy ( 36 MeV) and /cm at high energy (40 MeV and 90 Me…
