Semiconductor Laser with Electrically Modulated Frequency
B. Laikhtman, G. Belenky, S. Suchalkin
We propose a novel method to control the frequency of semiconductor lasers. The new technique allows fabricating three-terminal lasers with fast frequency tuning and the possibilit…
Fundamental Limitations on Gain of THz QCL
L. D. Shvartsman, B. Laikhtman
We analyze the main physical processes in quantum cascade lasers with spatial separation between the region of photon radiation and LO phonon emission providing depopulation of the…
Double well heterostructures for electric modulation of light
B. Laikhtman, S. Suchalkin, G. Belenky
The system of double quantum wells separated by barriers is suggested for switching and modulation of light. The system has potential for high operational speed and large modulatio…
Energy spectrum and optical absorption of superlattices under strong band inversion conditions
B. Laikhtman, S. Suchalkin, G. Belenky +1
We show that in superlattices with a strong band inversion no hybridization gap exists. There are two points where the bands are crossing and the spectrum has a shape of Dirac cone…
Direct and indirect exciton mixture in double quantum wells
B. Laikhtman
The exciton system in double quantum well is considered under condition when the ground state is the spatially indirect exciton. At high pumping growth of the exciton concentration…
Metamorphic InAs1-xSbx/InAs1-ySby superlattices with ultra-low bandgap as a Dirac material
Sergey Suchalkin, Gregory Belenky, Maksim Ermolaev +9
It was experimentally demonstrated that short-period metamorphic InAs1-xSbx/InAs1-ySby superlattices with ultra low bandgap have properties of a Dirac material. Cyclotron resonance…
