Abstract

We propose the lateral coupling of dual VCSEL cavities using a bow-tie shape connection for increasing the modulation bandwidth. The 3-D modeling shows no-noticeable radiation loss when two oxide-defined VCSEL cavities are coherently coupled. Transverse-mode switching offers a unique modulation concept that makes intensity modulation while total photon density inside the coupled cavities is unchanged under push-pull current modulation. Large modulation bandwidth free from relaxation oscillation frequencies can be expected. We fabricated 980nm laterally coupled cavity VCSELs with a bow-tie shape oxide aperture and demonstrated the transverse-mode switching under push-pull operations.
