摘要：
This disclosure describes a bottom surface emitting vertical cavity surface emitting laser (BSE VCSEL) with a lithographically defined aperture. The BSE VCSEL may be oxide-free. Two contacts are located above a substrate. An aperture and one or more active regions are located between two DBRs. A first contact is coupled to the substrate and the first DBR, which is below the aperture. A second contact is coupled to the second DBR, which is above the aperture.
