In some implementations, a vertical cavity surface emitting laser (VCSEL) device includes a substrate; a first mirror disposed over the substrate; a bonding layer disposed over the first mirror; and an active region disposed over the bonding layer. The substrate is a gallium arsenide (GaAs) substrate, and the active region is an indium phosphide (InP)-based active region.
