We present the modeling of an active nonlinear source designed for spontaneous parametric down-conversion in an AlGaAs waveguide. Electrically pumped InAs Quantum Dots embedded in the waveguide core provide the gain necessary for the lasing of a seco

We investigate the electromagnetic design of whispering gallery mode (WGM) terahertz (THz) resonators. Terahertz radiation is generated by difference-frequency mixing of two electrically pumped high-order near-infrared laser WGM's at room temperature

We demonstrate the operation of coupled-cavity terahertz frequency quantum-cascade lasers composed of two sub-cavities separated by an air gap realized by optical lithography and dry etching. This geometry allows stable, single mode operation with ty

We report on the design, fabrication and optical investigation of AlGaAs microcavities for THz Difference Frequency Generation (DFG) between Whispering Gallery Modes (WGMs), where the pump and DFG wavelengths (λ ≈ 1.3 μm and λ ≈ 75-150 μm, re

We report on an integrated GaAs disk/waveguide system. A millimeter-long waveguide is suspended and tapered on the chip over a length of 25 {\mu}m to evanescently couple to high Q optical whispering gallery modes of a GaAs disk. The critical coupling

International audience; A 2.8 THz metal-metal quantum cascade laser operating with a microtransverse-electromagnetic-horn antenna has been demonstrated. By comparing the far-field radiation pattern to a standard ridge cavity with a cleaved facet, a s

International audience; We report on the observation of self-amplified parametric downconversion in a selectively oxidized AlGaAs cavity that was designed to perform as a guided-wave optical parametric oscillator in the near infrared. To date, two te
