Abstract: A vertical cavity using a chirped heterostructure dual-period high-contrast grating (HCG) by simple fabrication is demonstrated. The reflectivity spectra of the vertical cavity were measured, consistent well with the calculated results. The mode characteristics of the vertical cavity with the chirped heterostructure dual-period HCG for the vertical-cavity surface-emitting laser (VCSEL) were investigated. The chirped heterostructure dual-period HCG can act as a metastructure to tailor the transmitted amplitude and phase for the beam shaping of the VCSEL. The vertical cavity with a chirped heterostructure dual-period HCG will be useful for VCSEL applications.
