Abstract
The present disclosure relates to shaping of optic beams at the inputs/outputs of a photonic chip, the spectral widening of the light coupled to this chip, and a method for manufacturing the chip. The photonic chip includes a light guiding layer supported by a substrate. The chip includes at least one light guiding structure made of silicon coupled on one side to a vertical coupler and on another side to an optical component integrated in the light guiding layer. The photonic chip has a front face on the vertical coupler side and a rear face on the substrate side. A collimation structure of digital lens type is integrated at the level of the rear face to collimate the mode size of the light beam incident on the lens and coming from the vertical coupler.
