WebMay 1, 2007 · The acoustic field shows asymmetric distribution along the X-axis because of the asymmetric structure of the inclined chirp IDT. Finally, acoustic field of a two-IDT … WebThis number of wavelengths is convenient for the output IDT 130, since the number is readily divisible into 16 sub-bands and also scales with an integer relationship to the third harmonic. It can be shown that the total length of the chirp IDT is the same as for a non-chirp input IDT (1.0306 mm), corresponding to a chirp time of 0.3145 ...

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.
