Patent ID: 7016557

Claim:
An optical chip having a substrate, optical conductors arranged on the top side of the substrate, at least one thermooptical structure, arranged on the top side of the substrate, for the purpose of influencing the optical properties of the optical conductors, and a cohesive, layered stiffening structure provided on the underside of the substrate, the stiffening structure and the respective thermooptical structure being provided in such a way that, seen in the top view of the chip, the stiffening structure extends in two directions perpendicular to each other at a distance from the respective thermooptical structure transversely over the substrate and/or along the free edge of the substrate, at least partially around the respective thermooptical structure, wherein said stiffening structure is constructed in the form of a cross which is arranged centrally on the substrate with the provision of diametrically opposite cut-outs.
