Interaction between Light and Sound at Structured Piezoelectric Interfaces for Gigahertz Endoscopy and Quantum Light Engineering (LSI-SPI)

Project funded by Research Council of Finland, grant 364037. Participating organisations named by the source: Aalto University. Funded amount: EUR 398,730, as stated by the source. Runs 2024-09-01 to 2028-08-31. Keywords: Nanotechnology. Source: OpenAIRE Graph, from the funder's project data (collected by OpenAIRE on 2024-09-13); national funding data, not CORDIS. Abstract given by the source: We often meet sound apart from the hearing itself: bats locating the objects; ultrasonic investigation in medicine; monitoring bridges and buildings. We will study a new mechanism for light-to-sound conversion in piezoelectrics. The novel idea is in combining the nanostructures acting as acoustic sources, with a special type of optical excitation. This enables complex acoustic beams with unusual properties such as all-optical steering. We will probe the quantum behavior of acoustic waves at room temperatures. We will fabricate the converters for gigahertz acoustic endoscopy for medical diagnostics and research. Better understanding of mechanisms for generating sound at the microscale will benefit the basic science and create applications in biomedical imaging and material science. Research will be conducted at Aalto University with its high-quality nanofabrication facilities and optical laboratories. Our project includes international collaboration and the training of new researchers.
