biostudies-literatureUnknown11(16)Honari-Latifpour MIntegrated planar lenses are critical components for analog optical information processing that enable a wide range of applications including beam steering. Conventional planar lenses require gradient index control which makes their on-chip realization challenging. Here, we introduce a new approach for beam steering by designing an array of coupled waveguides with segmented tails that allow for simultaneously achieving planar lensing and off-chip radiation. The proposed arrayed waveguide lens is built on engineering the evanescent coupling between adjacent channels to realize a photonic lattice with an equi-distant ladder of propagation constants that emulates the continuous parabolic index profile. Through coupled-mode analysis and full-wave numerical simulations, we show that selective eNanophotonics (Berlin, Germany)3679-3686https://www.ebi.ac.uk/biostudies/studies/S-EPMC11501650biostudies-literatureArrayed waveguide lens for beam steering.PMC11501650Miri MAHonari-Latifpour MMadamopoulos NEftekhar MABinaie AfalseArrayed waveguide lens for beam steering.Integrated planar lenses are critical components for analog optical information processing that enable a wide range of applications including beam steering.
