Abstract:
Improvement has been considered of an optoacoustic generator based on a structure with a Tamm plasmon as an active medium by means of the addition of an organic material (polydimethylsiloxane) layer with an extremely high thermal expansion coefficient. The simulation of the structure characteristics has been shown that the use of polydimethylsiloxane as an additional layer in the optoacoustic transducer structure is appropriate at frequencies up to 50 MHz. We have also shown that the addition of an organic layer leads to an increase in the efficiency of the optoacoustic transformation by four orders.
