In this study, a new theoretical calculation of metal-mode-filtered vertical-cavity surface-emitting laser (MMF-VCSEL) is proposed. The optimized number of P-DBR and the metal layer thickness are used. The effects of the metal mode filtered structure on the threshold gain of different transverse modes is analyzed. The MMF-VCSEL can operate in fundamental transverse mode under 8 μm oxide aperture compared with the conventional oxide-confined VCSEL. Benefit from the large oxide aperture and small metal aperture, the current crowding effect is effectively avoided and the heat distribution inside the VCSEL is improved.
