FDTD simulation of semiconductor plasmonic nano-lasers at 1550nm based on realistic semiconductor gain model: Square resonators and waveguide coupled rings

Two new nano-scale plasmonic-semiconductor laser resonator designs are simulated by multi-level multi-electron FDTD model, including a “square resonator” and a “waveguide coupled ring”. Both achieved stable lasing at 1550nm. Low temperature operation is also explored.
