Spectral Linewidth of Photonic Crystal Surface Emitting Lasers

The spectral linewidth of photonic crystal surface emitting lasers is evaluated using a heterodyne method utilizing two nominally identical devices. Linewidths of 100-200 kHz are obtained at modest output powers for these GaAs based 935 nm PCSELs. The natural linewidth is determined to be 71\pm 30 \...
