A vertical cavity surface emitting laser (VCSEL) has a top mirror structure with a surface, a light generation region, and a bottom mirror structure for reflecting light toward said top mirror structure. The VCSEL has a semiconductor portion with a surface that is disposed substantially planar with respect to the surface of the top mirror structure. At least one aperture-defining layer having an isolatable material is disposed in at least one of the bottom mirror structure and the top mirror structure. The aperture-defining layer has a conducting region, an insulating region having an aperture-defining surface for defining the conducting region, and a single trench adjacent to the insulating region for use in generating the insulating region. The trench having a continuous geometry for reducing the parasitic capacitance of the VCSEL.
