Femtosecond superradiance in multiple-section InGaN/GaN quantum well laser structures | | D. L. Boiko

29 Mar 2011 | | Abstract: | We analyze theoretically a possibility of the superradiant emission (SR) in
GaN-based quantum well (QW) laser heterostructures. Our model is based on
travelling wave Maxwell-Bloch equations predicts building up of macroscopic
coherences in the ensemble of carriers in the QWs. We show that SR is covered
by the Ginzburg-Landau equation for phase transition to coherent matter state.
The generation of superradiant pulses as short as 500 fs at peak powers of over
200 W has been predicted for InGaN/GaN heterostructure QWs with the peak
emission in the blue/violet wavelength range. | | Source: | arXiv, 1103.5507 | | Services: | Forum | Review | PDF | Favorites | |
