Electro-optical modulator for use in waveguide applications has a waveguide that forms an electrical capacitor with two oppositely doped semiconductor areas separated by a non-conducting capacitor insulation layer

摘要

Electro-optical modulator has at least a waveguide (300) that forms an electrical capacitor and has at least two wave-guiding semiconductor areas (310, 320) that are separated by a non-conducting capacitor insulation layer (340).
