Midinfrared Semiconductor Photonics - A Roadmap
J. R. Meyer, I. Vurgaftman, S. -Q. Yu +56
Semiconductor photonic devices operating in the midwave infrared (mid-IR, which we roughly define here as wavelengths spanning 3 to 14 microns) uniquely address a wide range of cur…
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…
Heterodyne coherent detection of the electric field temporal trace emitted by frequency-modulated comb lasers
Baptiste Chomet, Salim Basceken, Djamal Gacemi +6
Frequency-modulated (FM) combs are produced by mode-locked lasers in which the electric field has a linearly chirped frequency and nearly constant amplitude. This regime of operati…
Ultra-sensitive heterodyne detection at room temperature in the atmospheric windows
Mohammadreza Saemian, Livia Del Balzo, Djamal Gacemi +9
We report room temperature heterodyne detection of a quantum cascade laser beaten with a local oscillator on a unipolar quantum photodetector in two different atmospheric windows,…
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…
Quasi-static and propagating modes in three-dimensional THz circuits
Mathieu Jeannin, Djamal Gacemi, Angela Vasanelli +6
We provide an analysis of the electromagnetic modes of three-dimensional metamaterial resonators in the THz frequency range. The fundamental resonance of the structures is fully de…
Coupling of a surface plasmon with localized subwavelength microcavity modes
Pierre Jouy, Yanko Todorov, Angela Vasanelli +3
Mid-infrared photonic modes of a periodically patterned metal-dielectric-metal structure have been investigated theoretically and experimentally. We have observed an anticrossing b…
