Abstract: An avalanche photodiode includes a stack of layers. The stack of layers includes an avalanche diode (of PN or PIN type) and a layer having quantum dots located therein. The stack of layers further includes: a charge extraction layer over the layer which includes quantum dots; a transparent conducting layer over the charge extraction layer; and an insulating layer over the transparent conducting layer. The quantum dots includes ligands formed by molecules of dopants.

Abstract: An optical device includes a layer having a face configured to be traversed by light at an operating wavelength. The face of the layer includes a fractal structure lacking rotational symmetry such as a fractal structure that corresponds to a fractal expressed in an L-system. The fractal structure is formed by recesses that penetrate into the layer from the face. The recesses have a depth which is less that a thickness of the layer.
