Optical gain of interdiffused GaInNAs/GaAs quantum wells
نویسندگان
چکیده
A self-consistent model for the band structure and optical gain spectra in interdiffused GaxIn1−xN0.04As0.96/ GaAs single quantum wells are studied theoretically using Fick’s Law and the Fermi Golden Rule. Due to quantumwell interdiffusion, the peak gain and its peak vary with the annealing time. Our results show that the interdiffusion technique can be used to tune the operation wavelength for multi-wavelength applications without degradation of device performance.

متن کاملContactless electroreflectance approach to study the Fermi level position in GaInNAs/GaAs quantum wells
A fruitful approach to study the Fermi level position in GaInNAs/GaAs quantum wells QWs has been proposed in this paper. This approach utilizes contactless electroreflectance CER spectroscopy and a very simple design of semiconductor structures. The idea of this design is to insert a GaInNAs quantum well QW into a region of undoped GaAs layer grown on n-type GaAs substrate. The possible pinning...

Hot electron light emission and lasing in semiconductor heterostructure (Hellish) devices are surface emitters the operation of which is based on the longitudinal injection of electrons and holes in the active region. These devices can be designed to be used as vertical cavity surface emitting laser or, as in this study, as a vertical cavity semiconductor optical amplifier (VCSOA). This study i...
متن کاملPhotoconductivity and photoluminescence under bias in GaInNAs/GaAs MQW p-i-n structures
The low temperature photoluminescence under bias (PLb) and the photoconductivity (PC) of a p-i-n GaInNAs/GaAs multiple quantum well sample have been investigated. Under optical excitation with photons of energy greater than the GaAs bandgap, PC and PLb results show a number of step-like increases when the sample is reverse biased. The nature of these steps, which depends upon the temperature, e...
