GaN-based surface-emitting lasers using high contrast grating
نویسندگان
چکیده
GaN-based surface-emitting lasers (SELs) using high contrast grating (HCG) with AlN/GaN distributed Bragg reflectors were reported. The laser device achieved a threshold energy density of about 0.56 mJ/cm and the lasing wavelength was at 393.6 nm with a high degree of polarization of 73% at room temperature. The resonant mode and polarization characteristics matched to the theoretical prediction. GaN-based SELs using HCG supported by the Fano resonance can be potential for development of blue surface emitting laser sources KeywordsGaN, surface-emitting laser, high contrast grating, Fano resonance.

GaN-based vertical-cavity surface-emitting lasers (VCSELs) are expected to exhibit several advantages over their already widely used edge-emitting counterparts, including lower manufacturing costs, circular output beams, and longer lifetime. However, in contrast to the great success of GaN-based edge-emitting lasers in recent years, GaN-VCSELs still face significant challenges. Electrically pum...
