Abrégé
(EN) In some examples, an apparatus comprises: a first photodiode to sense a first component of light associated with a first wavelength, and a second photodiode configured to sense a second component of the light associated with a second wavelength, the first component and the second component being associated with, respectively, a first wavelength and a second wavelength. The apparatus further comprises a first optical structure and a second optical structure positioned over, respectively, the first photodiode and the second photodiode. The first optical structure is configured to increase a propagation path of the first component of the light within the first photodiode and has a first optical property based on the first wavelength. The second optical structure is configured to increase a propagation path of the second component of the light within the second photodiode, and has a second optical property based on the second wavelength.
(FR) Selon certains exemples, un appareil comprend : une première photodiode pour détecter une première composante d'une lumière associée à une première longueur d'onde, et une seconde photodiode configurée pour détecter une seconde composante de la lumière associée à une seconde longueur d'onde, la première composante et la seconde composante étant associées respectivement à une première longueur d'onde et à une seconde longueur d'onde. L'appareil comprend en outre une première structure optique et une seconde structure optique, respectivement positionnées sur la première photodiode et la seconde photodiode. La première structure optique est configurée pour accroître un trajet de propagation de la première composante de la lumière à l'intérieur de la première photodiode et présente une première propriété optique fondée sur la première longueur d'onde. La seconde structure optique est configurée pour accroître un trajet de propagation de la seconde composante de la lumière à l'intérieur de la seconde photodiode, et présente une seconde propriété optique fondée sur la seconde longueur d'onde.
