The influence of In surface segregation and internal fields induced by polarization charges on the band structure on InGaN/GaN quantum wells is studied in the frame of 6×6 multiband model. The indium surface segregation leads to the blue shift of the transition energy (70 meV for the segregation length 1nm at both heterointerfaces) while the piezoelectric polarization itself causes the red shift....
Using numerical modeling, influence of tuning the lasing frequency within the gain band on the modulation response of quantum-well heterolasers in the GaInAs-GaInAsP system versus the modulation frequency of pump current is investigated. It is established that maximum values of the frequency width of the response band and possibilities of realization of high-speed regimes at signal transmission in...
We report the spatial anisotropy of the acoustooptical figure of merit M2 in LiNbO3:MgO and GaP crystals. The analysis is based on the indicative surfaces being calculated for different geometries of the acoustooptical diffraction. Basing on these results the most efficient geometries of the acoustooptical cells made of these crystals are determined. It give a possibility to increase the application...
