Optical coupling system, corresponding device and method

A device, comprising:

• a photonics integrated circuit, which, in operation, converts one or more of:
• at least one electrical signal into an optical signal;
• and
• at least one optical signal into an electrical signal;
• and
• an optical coupling including a body made of a curable material, the body having:
• a first surface directly cured onto a portion of a surface of the photonics integrated circuit and optically coupled with the portion of the surface of the photonics integrated circuit;
• and
• a second surface including an array of lenses integral with the body, wherein the array of lenses is configured to couple to an optical fiber connector.

A method of manufacturing an optical coupling, comprising:

• shaping curable material on a photonics integrated circuit into a body positioned on a portion of a surface of the photonics integrated circuit;
