Abstract
Example embodiments relate to an electro-optical device that includes a vertical p-i-n diode waveguide. The electro-optical device includes a waveguide portion adapted for propagating a multimode wave, the waveguide portion including an intrinsic semiconductor region of the vertical p-i-n diode, a first contact and a second contact for electrically contacting a first electrode and a second electrode of the vertical p-i-n diode. The device also includes an input section for coupling radiation into the waveguide portion and an output section for coupling radiation out of the waveguide portion. The input section, the output section, and the waveguide portion are configured to support a multimode interference pattern for the multimode wave with an optical field with a lateral inhomogeneous spatial distribution in the waveguide portion including regions with higher optical field intensity and regions with lower optical field intensity. The second contact physically contacts the second electrode.
