(a) Top view of the LBE indicating the emitter channels and the beam scanning parameters. (b) Calculated beam scanning range (ΔΨ) for the proposed end-fire OPA when \(\Delta \varphi\) is varied between + π and − π. (c) The simulated far-field profile of the emitted line beam showing the main and side lobes emanating from a 32-channel OPA with \({\Lambda }_{{{\text{ch}}}}\) = 3 µm and Wtp = 500 nm.
