The optical absorptions are calculated in an InAs/GaSb-based type II and broken-gap quantum well under applied electric field. Two absorption peaks were observed through intraband transitions within the same material layer. The absorption induced by the interlayer transition is rather weak due to the small overlap of electron and hole wavefunctions. The optical absorption can be significantly affected by the applied electric field. Our results suggest that InAs/GaSb-based type II and broken-gap QWs can be employed as two-colour photodetectors, which can be controlled by the applied electric field.

Hexagonal Manganites

Optical absorption of orthorhombic and hexagonal manganites RMnO3 (R= Pr3+, Gd3+, Sm3+, Eu3+, Ho3+, Tm3+, Er3+, and Yb3+) were studied in polarized light in the near- and mid-infrared range for the temperature range 80 - 300 K. Several spectral features associated with 4f-4f transitions of R3+ ions were found in the transparency window of RMnO3. Anisotropy of the absorption spectra in the range of multiplet 4f-4f transitions and changes in populations of the multiplet levels with temperature were observed.
