Abstract:
A photonic chip includes a connecting means, a substrate, and a waveguide layer. The photonic integrated waveguide and the optical fiber each have a front end portion. The connecting means includes a groove configured to receive the front end portion of the optical fiber. The groove is essentially U-shaped in its cross section, and the groove has a bottom surface and two inner side surfaces. A least one of both inner side surfaces of the U-shaped groove has a coating of an elastic material configured to hold in place the optical fiber after it is inserted into the groove. The invention further relates to an optical device which includes a photonic chip and an optical fiber, as well as a method or production of such a photonic chip.

Claim (Index 14):
A method of producing the photonic chip according to  claim 1 , comprising:\n (a) providing a photonic chip comprising a substrate and a waveguide layer which is provided on or within an upper portion of the substrate and which defines a photonic integrated waveguide, wherein the photonic integrated waveguide has a front end portion, which has a front surface and an optical axis; (b) etching a U-shaped groove having a bottom surface and two inner side surfaces into the photonic chip, the groove essentially extending from the front surface of the front end portion of the photonic integrated waveguide in the direction of the optical axis of the front end portion of the photonic integrated waveguide; and (c) applying a coating of an elastic material on at least one of the inner side surfaces of the U-shaped groove, (d) wherein the groove and the coating(s) of the inner side surfaces are configured to receive and hold in place a front end portion of an optical fiber.
