Abstract :
We found alternate oscillations in AlGaAs/GaAs single-quantum-well (SQW) quasi-stadium laser diodes (QSLD). The alternate oscillations in QSLD can be well explained by the interactions of two different cavity modes due to the geometrical symmetry of QSLD. We also showed the alternate oscillation frequencies are inversely proportional to the amplitudes of two different cavity modes.
