Low-loss and wideband acoustic delay lines
WebThe acoustic mode and LN cut were selected as S 0 and Z-cut for optimal optical waveguiding and aligning the highest strain component with the maximum photoelastic coefficient (P i j). Z-cut LN is isotropic in-plane in both refractive index and photoelastic effect, allowing flexible layout of optical WGs.In comparison to other cuts of LN, it also … Web10 mei 2024 · We present the first group of GHz S0 mode low-loss and wide-band acoustic delay lines. The acoustic delay lines use single-phase unidirectional transducers design to launch and...
