英文摘要	The present invention relates to an electro-optical device comprising a vertical p-i-n diode waveguide (100), the device comprising a waveguide portion (900) adapted for propagating a multimode wave, the waveguide portion (900) comprising an intrinsic semiconductor region (510) of the vertical p-i-n diode, a first contact (810) and a second contact (820) for electrically contacting a first electrode (400) and a second electrode (520) of the vertical p-i-n diode. The device also comprises an input section (102) for coupling radiation into the waveguide portion (900) and an output section for coupling radiation out of the waveguide portion (900). The inlet section (102), the output section (104) and the waveguide portion (900) are being configured for inducing a multimode interference pattern for the multimode wave to form an optical field with a lateral inhomogeneous spatial distribution in the waveguide portion (900) comprising regions with higher optical field intensity and regions with lower optical field intensity, the second contact (820) physically contacting the second electrode in at least one region of the waveguide with lower optical field intensity.
