Low loss silicon waveguides for the terahertz spectral region
Chip scale terahertz dielectric waveguides, consisting out of high resistivity silicon as a core material have been fabricated. The waveguide loss is measured to be similar to 1dB/cm at both 1 THz and 2.5 THz

InAs/AlSb quantum cascade lasers operating at 6.7 µm
International audienceQuantum cascade lasers based on the InAs/AlSb material system have been realised. The optical confinement is obtained using a plasmon waveguide with n+-InAs cladding layers. In pulse mode the lasers emit close to 6.7 μm with a threshold current density of 5 kA/cm2 at 90 K. The maximum operating temperature is 220 K
