Under the guidance of Dr. Igor Zutic, researched theoretical operation of spin lasers,
accounting for the polarization of electron and hole populations along with the spin
relaxation times of carriers.
Investigated the effects of carrier polarization on lasing threshold using Mathematica to
produce numerical solutions of coupled rate equations. Found threshold reduction to
exceed limits reported by other published authors.
Conducted large-signal analysis on spin-laser operation. Discovered non-monotonic
trends in dampening of relaxation oscillations in photon output density.
Discovered the desirably short decay time—a measure of relaxation to steady-state values
in lasers—is achieved for short spin relaxation times. The behavior was related to
Matthiessen’s rule.
Modified rate equations to account for Auger process.
Generated eye diagrams for spin lasers with amplitude and polarization modulations.
These results will be submitted for publication.
Related short decay time to a significant reduction in bit-error rate for a digital data signal
generated by a spin laser.
