52° tilted SEM image of (a) FIB milled Bragg grating on bulk LN (the scale bar denotes 5 μm) and (b) the trenches with conical cross sections. (c) Transmission spectrum of the structure in panel (a) shows high insertion loss up to 51 dB. (d) -plane (side view) FDTD field simulation showing transmission losses due to vertical plane scattering arising from conicity and poor confinement.
