Abstract
The photonic integrated device for converting a light signal into sound comprises—a substrate having a substrate surface, an optical waveguide on the substrate surface, a photo-acoustic conversion body, comprising at least one volume of fractionally light absorbing material or formed entirely of fractionally light absorbing material, wherein a width of the photo-acoustic conversion body is greater than a width of the optical waveguide and means for enhancing distribution of light from the optical waveguide over the photo-acoustic conversion body.
