Summary:To provide an optical device having a hybrid absorber.SOLUTION: An optical device includes a first photodiode, a second photodiode and a hybrid absorber. The hybrid absorber is arranged above the first photodiode and the second photodiode. The hybrid absorber includes a color filter layer and a plurality of metal-insulator-metal structures. The color filter layer includes a first color filter arranged on the first photodiode and a second color filter arranged on the second photodiode, and the first color filter is different from the second color filter. The plurality of metal-insulator-metal structures are arranged above the first photodiode and are not arranged above the second photodiode.SELECTED DRAWING: Figure 1 【課題】ハイブリッド吸収体を有する光学装置を提供すること。【解決手段】光学装置は、第１のフォトダイオード、第２のフォトダイオード及びハイブリッド吸収体を含む。ハイブリッド吸収体は、第１のフォトダイオード及び第２のフォトダイオードの上方に配置される。ハイブリッド吸収体は、カラーフィルタ層及び複数の金属－絶縁体－金属構造体を含む。カラーフィルタ層は、第１のフォトダイオードに配置された第１のカラーフィルタと、第２のフォトダイオードに配置された第２のカラーフィルタとを含み、第１のカラーフィルタは、第２のカラーフィルタとは異なる。複数の金属－絶縁体－金属構造体は、第１のフォトダイオードの上方に配置され、第２のフォトダイオードの上方に配置されない。【選択図】図１
