Photodetector device with an optical guide element

Method of manufacturing a photodetector device, comprising at least:

• the forming of at least one optical guide element;
• the forming of at least one electronic component for converting light into an electrical signal, configured to detect light at least on the side of a first surface arranged in front of the optical guide element and on the side of a second surface opposite to the first surface;
• the forming of at least one reflective layer arranged on the side of the second surface of the electronic component;
• the forming of at least one optical component arranged between the reflective layer and the optical guide element and at least partially transparent to the light to be detected by the electronic component;
• and wherein the reflective layer is formed in such a way that it forms at least one reflective surface conformal to a non-planar surface of the optical component having the reflective layer arranged thereon.
