Heterodyne coherent detection of phase modulation in a mid-infrared unipolar device
Hamza Dely, Baptiste Chomet, Thomas Bonazzi +8
Phase modulation is demonstrated in a quantum Stark effect modulator designed to operate in the mid-infrared at wavelength around 10 m. Both phase and amplitude modulation are s…
Highly coherent phase-lock of an 8.1 m quantum cascade laser to a turn-key mid-IR frequency comb
B. Chomet, D. Gacemi, O. Lopez +5
A continuous-wave Fabry-Perot quantum cascade laser (QCL) emitting at 8.1 m operating in the single mode regime has been coherently phase locked to a turn-key low-noise commerci…
High temperature metamaterial terahertz quantum detector
Mathieu Jeannin, Thomas Bonazzi, Djamal Gacemi +7
We demonstrate a high temperature performance quantum detector of Terahertz (THz) radiation based on three-dimensional metamaterial. The metamaterial unit cell consists of an induc…
Optomechanical THz detection with a sub-wavelength resonator
Cherif Belacel, Yanko Todorov, Stefano Barbieri +3
The terahertz (THz) spectral domain offers a myriad of applications spanning chemical spectroscopy, medicine, security and imaging[1]. It has also recently become a playground for…
Continuous-wave coherent imaging with terahertz quantum cascade lasers using electro-optic harmonic sampling
Marco Ravaro, Vishal Jagtap, Giorgio Santarelli +5
We demonstrate a coherent imaging system based on a terahertz (THz) frequency quantum cascade laser (QCL) phase-locked to a near-infrared fs-laser comb. The phase locking enables c…
Optical properties of metal-dielectric-metal microcavities in the THz frequency range
Yanko Todorov, Lorenzo Tosetto, Jean Teissier +6
We present an experimental and theoretical study of the optical properties of metal-dielectric-metal structures with patterned top metallic surfaces, in the THz frequency range. Wh…
