Abstract
An integrated transducer device includes an optical transducer and an acoustic transducer integrally joined with the optical transducer. The acoustic transducer includes a membrane responsive to acoustic signals, the membrane being aligned with the optical transducer such that optical signals emitted or received by the optical transducer pass through the membrane. A propagation direction of the acoustic signals emitted or received by the acoustic transducer is collinear with a propagation direction of the optical signals emitted or received by the optical transducer.
