Observation of the collective Coulomb blockade effect in a constant-current-driven high-speed light-emitting diode

摘要

We have investigated the intensity squeezing bandwidth of sub-Poissonian light generated by a high-speed light-emitting diode. The squeezing bandwidth of a constant-current-driven light-emitting diode is proportional to a driving current in a lower-current regime and approaches a constant in a higher-current regime. This dependence on driving current is well explained by the contributions of the thermionic emission time and the radiative lifetime to the squeezing bandwidth. (C) 1997 Optical Society of America.
