Photocurrent noise in multi-quantum-well infrared photodetectors
We report on photocurrent noise in AlGaAs/GaAs quantum-well infrared photodetectors having nominally the same design, except the number of wells N . The power spectral density does not scale as the inverse of the number of wells N in the presence of infrared radiation. These features can be understood by taking into account the nonlinearity arising at high infrared power as a consequence of the...
متن کاملNoise in single quantum well infrared photodetectors
The noise of the dark current and photocurrent is an important factor in operation of the quantum well infrared photodetectors ~QWIPs!. For typical operating conditions, the main source of fluctuations in QWIPs is generationrecombination noise associated with the excitation of carriers from the QWs into the continuum and their capture into the QWs. For applications the study of noise in QWIPs i...

متن کاملSilicon-Germanium multi-quantum well photodetectors in the near infrared.
Single crystal Silicon-Germanium multi-quantum well layers were epitaxially grown on silicon substrates. Very high quality films were achieved with high level of control utilizing recently developed MHAH epitaxial technique. MHAH growth technique facilitates the monolithic integration of photonic functionality such as modulators and photodetectors with low-cost silicon VLSI technology. Mesa str...
