Abstract

We present a vertical-cavity surface-emitting laser (VCSEL) where a GaAs “half-VCSEL” is attached to a

silicon-based dielectric distributed Bragg reflector using ultra-thin divinylsiloxane-bis-benzocyclobutene

(DVS-BCB) adhesive bonding, creating a hybrid cavity where the optical field extends over both the GaAs-

and the Si-based parts of the cavity. A VCSEL with an oxide aperture diameter of 7 µm and a threshold

current of 0.7 mA provides 1.5 mW output power at 844 nm. With sufficient damping of the modulation

response, set by the photon lifetime, the VCSEL exhibits a modulation bandwidth >10 GHz and can

transmit data up to 15
