    Abstract: A VCSEL device includes a substrate and a first DBR structure disposed on the substrate. The VCSEL device further includes a cathode contact disposed on a top surface of the first DBR structure. In addition, the VCSEL device includes a VCSEL mesa that is disposed on the top surface of the first DBR structure. The VCSEL mesa includes a quantum well, a non-circularly-shaped oxide aperture region disposed above the quantum well, and a second DBR structure disposed above the non-circularly-shaped oxide aperture region. In addition, the VCSEL mesa includes a selective polarization structure disposed above the second DBR structure and an anode contact disposed above the selective polarization structure.
