Investigation of Lasing in Highly Strained Germanium at the Crossover to Direct Band Gap
Francesco Armand Pilon, Yann-Michel Niquet, Jeremie Chretien +8
Efficient and cost-effective Si-compatible lasers are a long standing wish of the optoelectronic industry. In principle, there are two options. For many applications, lasers based…
Far-infrared quantum cascade lasers operating in AlAs phonon Reststrahlen band
K. Ohtani, M. Beck, M. J. Süess +6
We report on the operation of a double metal waveguide far-infrared quantum cascade laser emitting at 28 m, corresponding to the AlAs-like phonon Reststrahlen band. To avoid abs…
Accurate strain measurements in highly strained Ge microbridges
A. Gassenq, S. Tardif, K. Guilloy +16
Ge under high strain is predicted to become a direct bandgap semiconductor. Very large deformations can be introduced using microbridge devices. However, at the microscale, strain…
Room-temperature transverse-electric polarized intersubband electroluminescence from InAs/AlInAs quantum dashes
V. Liverini, L. Nevou, F. Castellano +4
We report the observation of transverse electric polarized electroluminescence from InAs/AlInAs quantum dash quantum cascade structures up to room temperature. The emission is attr…
