Abstract

Un réseau de lentilles comprend de multiples premières couches diélectriques (212) et de multiples premières structures de réseau (211). Les premières structures de réseau (211) et les premières couches diélectriques (212) sont empilées de manière alternée dans une première direction. Chacune des premières structures de réseau (211) comprend une ou plusieurs premières unités de réseau (211a) agencées en un réseau. De multiples premières unités de réseau (211a) situées à la même position relative dans les multiples premières structures de réseau (211) sont disposées coaxialement dans la première direction. Dans une première structure de réseau comprenant de multiples premières unités de réseau (211a), au moins deux des premières unités de réseau (211a) présentent un changement progressif de taille dans une direction du réseau.
