Development of high power quantum well lasers at RRCAT
T. K. Sharma, Tapas Ganguli, V. K. Dixit +9
We at RRCAT have recently developed high power laser diodes in the wavelength range of 740 to 1000 nm. A typical semiconductor laser structure is consisted of about 10 epilayers wi…

Alloying induced degradation of the absorption edge of InAs_{x}Sb_{1-x}
Bhavtosh Bansal, V. K. Dixit, V. Venkataraman +1
InAs_{x}Sb_{1-x} alloys show a strong bowing in the energy gap, the energy gap of the alloy can be less than the gap of the two parent compounds. We demonstrate that a consequence…
