A PHOTONIC INTEGRATED DEVICE FOR CONVERTING A LIGHT SIGNAL INTO SOUND |
(57) 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.
