Abstract: In one example, a vertical cavity surface emitting laser (VCSEL) may include an active region to produce light at a wavelength, an emission surface to emit the light at the wavelength, a first oxide region spaced apart from the active region by a distance of at least a half-wavelength of the wavelength, a first oxide aperture in the first oxide region, a second oxide region between the first oxide region and the second oxide region, and a second oxide aperture in the second oxide region. The emitted light may have a divergence angle that is based on the respective positions and thicknesses of the first oxide region and the second oxide region.

Abstract: A method of compensating for electromagnetic radiation. The method may include measuring electromagnetic radiation emanating from circuitry at a first frequency and adjusting at least one of the electrical settings of the circuitry based on the measurement of the electromagnetic radiation to reduce the electromagnetic radiation at the first frequency emanating from the circuitry.
