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. WebAug 2, 2024 · The design of the chirp IDT is determined by the set of frequencies f n. A natural choice for f n is an evenly spaced set, f n= f 1 + (n 1) f; f= f N f 1 N 1; (3) leading to the following recurrence relation for the cell periodicity: n+1 = 1 1 n + f v SAW (4) With this chirp geometry, maximal pulse compression is achieved by applying an input ...

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.
