WebDec 21, 2024 · The AO unit consists of a wide bandwidth chirp interdigital transducer (IDT) on a 20 µm thick suspended crystalline 128° YX LiNbO 3 membrane, a light blocker with a 20 µm hole near the entrance, and an active lens near the exit. The 20 µm thickness of the floating membrane significantly enhanced surface acoustic wave (SAW) confinement. WebThe pitch of the chirp transducer changes from that of the gratings to a value slightly lower (in this example by about 0.9%) or slightly larger (in general case). As a result the larger maximum of the chirp IDT conductance shifts closer to the Bragg frequency of reflectors.
