    • Limits of strong mode confinement in microdisk terahertz quantum-cascade lasers 

      Fasching, G.; Benz, A.; Andrews, A.M.; Unterrainer, K.; Zobl, R.; Roch, T.; Schrenk, W.; Strasser, G.; Tamošiūnas, Vincas (CLEO/QELS and PhAST 2007 : conference on lasers and electro-optics; quantum electronics and laser science conference, May 6-11, 2007; Photonic applications, systems and technologies conference, May 7-10, 2007, Baltimore Maryland, USA, 2007)
      We present microdisk terahertz quantum-cascade lasers with dimensions comparable to the spatial mode distribution inside the microcavity and present 3D Finite-Difference Time-Domaine simulations which are in good agreement ...
