Closed mode structures in large rectangular closed resonators based on AlGaAs/GaAs heterostructures

The study considers mode structure formation in large size planar rectangular cavities. Cavity samples with cleaved edges were based on AlGaAs/GaAs QW laser heterostructures at wavelengths of 1040‐60 nm. Mode structure visualization and control of their spatial configuration by external optical excitation are demonstrated. A 2D model was also created that describes mode configurations formation when the resonator design is varied.
