Abstract: Some embodiments of the present invention are directed to an aperture for a laser for high-bandwidth communication. The laser may include an active region configured to emit light parallel to an optical axis and an emission surface spaced from the active region and through which the light is emitted. The laser may also include an aperture positioned along the optical axis between the active region and the emission surface, where the aperture has a cross-sectional area in a plane perpendicular to the optical axis, and where the cross-sectional area defines a non-circular shape. In some embodiments, the non-circular shape may have at most one axis of symmetry. The aperture may be configured to reduce a spectral bandwidth of the light emitted by the laser and a relative intensity noise of the laser.
