Claim 0:
1. An optical waveguide-transmitter apparatus for imaging an examination region via ultrasonic waves generated by light beams, comprising:
a substrate, the substrate including a first semiconductor material;
a carrier layer, the carrier layer being on the substrate;
at least one transmitter-optical waveguide, the at least one transmitter-optical waveguide including a second semiconductor material with a refractive index greater than a refractive index of the carrier layer, and the at least one transmitter-optical waveguide including at least one longitudinal side surrounded by the carrier layer; and
a further transmitter-optical waveguide, the further transmitter-optical waveguide including at least one longitudinal side surrounded by the carrier layer,
wherein the at least one transmitter-optical waveguide and the further transmitter-optical waveguide are configured to guide the light beams simultaneously,
the at least one transmitter-optical waveguide includes an optical absorption layer configured to convert the light beams to generate ultrasonic waves which are decoupled into the examination region for an ultrasonic imaging process, the optical absorption layer being at an end of the at least one transmitter-optical waveguide facing toward the examination region, and
the further transmitter-optical waveguide is configured for an optoacoustic imaging process.
