Calibration-assisted stress-optic phase programming for a 3D-printed optical neural-network frontend

We report a calibration-assisted stress-optic phase-programming method for a 3D-printed optical neural-network (ONN) frontend. Full-vector stress-optic modeling gives a full-stress effective-index shift of Δ ⁢ 𝑛 e f f = − 2 . 1 2 8 4 × 1 0 − 4 at 850 nm, setting the phase-length...
