Abstract :
In this study, additionally, eigen modes under the different spatial distribution profiles of scatterers, and the Q factor of the modes are investigated and they are experimentally confirmed using the system in which quantum dot colloids serve as laser gain. Our main aim is to investigate the impulse response of the two-dimensional random system utilizing FDTD.
