Summary:To provide an environmentally protected photonic integrated circuit (PIC) and an optoelectronic system including the PIC.SOLUTION: The invention relates to an environmentally protected PIC (1), including an InP-based substrate (2) having a first surface (3) that at least partially includes an InP-based optical waveguide (4), and a dielectric protective layer (5) arranged so as to cover at least the first surface of the InP-based substrate and the InP-based optical waveguide. The dielectric protective layer is configured to protect the PIC from environmental contaminants, to enable confinement of optical radiation in the dielectric protective layer in at least one direction that traverses a direction of propagation of the optical radiation, and to allow exchange of the optical radiation between the InP-based optical waveguide and the dielectric protective layer. The invention also relates to an opto-electronic system (18) including the PIC.SELECTED DRAWING: Figure 1A 【課題】環境保護されたフォトニック集積回路(PIC)、およびPICを含む光電子システムを提供すること。【解決手段】本発明は、少なくとも部分的にInPベースの光導波路(4)を含む第1の表面(3)を有するInPベースの基板(2)と、少なくともInPベースの基板の第1の表面およびInPベースの光導波路を覆うように配置された誘電体保護層(5)と、を備えた、環境保護されたPIC(1)に関する。誘電体保護層は、上記PICを環境汚染物質から保護し、光放射の伝播方向を横切る少なくとも一方向において誘電体保護層に光放射を閉じ込めることを可能にし、InPベースの光導波路と誘電体保護層の間で光放射の交換を可能にするように構成される。本発明はまた、上記PICを含む光電子システム(18)に関する。【選択図】図1A
