Observation of long turn-on delay in pulsed quantum cascade lasers
E. D. Cherotchenko, V. V. Dudelev, D. A. Mikhailov +16
We present an experimental study of the turn-on delay in pulsed mid-infrared quantum cascade lasers. We report the unexpectedly long delay time depending on the pumping current, wh…
Optical power detector with broad spectral coverage, high detectivity and large dynamic range
Jussi Rossi, Juho Uotila, Sucheta Sharma +6
Optical power measurements are needed in practically all technologies based on light. Here we report a general-purpose optical power detector based on the photoacoustic effect. Opt…
Photoacoustic characteristics of carbon-based infrared absorbers
Jussi Rossi, Juho Uotila, Sucheta Sharma +5
We present an experimental comparison of photoacoustic responsivities of common highly absorbing carbon-based materials. The comparison was carried out with parameters relevant for…
Optical phonon scattering of cavity polaritons in an electroluminescent device
A. Delteil, A. Vasanelli, P. Jouy +5
A signature of the scattering between microcavity polaritons and longitudinal optical phonons has been observed in the electroluminescence spectrum of an intersubband device operat…
Radiative quantum efficiency in an InAs/AlSb intersubband transition
C. Faugeras, A. Wade, A. Leuliet +8
The quantum efficiency of an electroluminescent intersubband emitter based on InAs/AlSb has been measured as a function of the magnetic field up to 20T. Two series of oscillations…
