Abstract(in Japanese) (See Japanese page)
Abstract(in English) We propose the lateral coupled cavity VCSEL by using a bow-tie connection for enhancing the modulation bandwidth. Two oxide-defined VCSEL cavities are coherently coupled. Transverse-mode switching offers a unique modulation view that makes intensity modulation while total photon density inside the coupled cavities is fixed under push-pull current modulation. Large modulation bandwidth free from relaxation oscillation frequencies can be expected. We have fabricated 980nm laterally coupled cavity VCSELs with a bow-tie shape oxide aperture and demonstrated the transverse-mode switching under push-pull operations.
