  • Managing back-side processing of photonic integrated circuits
    Patent number: 12541059
    Abstract: An article of manufacture comprises a bottom volume comprising a first region composed of a first material characterized by a first index of refraction (IOR) and having a first thickness, and thinned regions in which a portion of the first material is absent or has a thickness less than the first thickness; a middle volume on top of the bottom volume and comprising a second material characterized by a second IOR smaller than the first IOR; and a top volume on top of the middle volume and comprising alignment structures, and a photonic structure; where the top and middle volumes are in contact at an interface plane, and spatial coordinates specify two-dimensional positions, within at least one thinned region in a second plane parallel to the interface plane and with respect to the alignment structures, of portions of the photonic structure in a first plane parallel to the interface plane.
