Abstract

The monolithic integration of all key photonic components (11–16) of an integrated-optical microsystem (1) based on organic semiconductors is disclosed. Examples of such components (11–16) are light sources (11), photodetectors (12), photovoltaic power generators (12), field-effect transistors (13, 14), resistors, capacitors (15), or waveguiding structures (11, 12). The components (11–16) are arranged on a common substrate (20), are compatible with each other, can be manufactured simultaneously and can be operated simultaneously. At least one of the components (11–14) comprises a layer (23) of organic semiconductor material. Each component (11–16) comprises a plurality of layers (21–26), at least one of which (21) has identical physical and chemical characteristics in at least two components (11–16). The large number and diversity of photonic devices that can be monolithically integrated allows a higher degree of integration, of functionality and of system complexity than was practical with the state of the art.
