We show in simulation and experiment that the coherent coupling of electric fields between elements a triangular photonic crystal vertical cavity surface emitting laser array can be adjusted into antiguided supermodes with approximately equal injection each element. The dominant are found by complex waveguide mode identified number arrangement side-lobes their Fourier-transformed far-field beam...

A typical self-mode-locked vertical-external-cavity surface-emitting laser must operate at the edge of stable region resonant cavity. Its minimal pump spot on gain chip is used as a soft aperture. By comparing with continuous-wave (CW) laser, pulsed focused more tightly due to Kerr-lens effect. This mitigates cavity loss in comparison CW such that successive mode-locking can be initiated. The d...
