Abstract: A waveguide for guiding an electro-magnetic wave comprises: a first waveguide part; and a second waveguide part; wherein the first waveguide part has a first width in a first direction (Y) perpendicular to the direction of propagation of the electro-magnetic wave and the second waveguide part has a second width in the first direction (Y), wherein the second width is larger than the first width; and wherein the first and the second waveguide parts are spaced apart by a gap in a second direction (Z) perpendicular to the first and second planes in which the waveguide parts are formed, wherein the gap has a size which is sufficiently small such that the first and second waveguide parts unitely form a single waveguide for guiding the electro-magnetic wave.A photonic integrated circuit component, a sensor and an actuator comprising the waveguide are disclosed.

Abstract: A sensor structure for an acoustical pressure sensor. The structure comprises an optical waveguide closed-loop resonator and a plurality of sensor elements, wherein the individual sensor elements of the plurality of sensor elements are configured to be affected by an acoustical pressure wave such that a physical property of the individual sensor element is changed. Further, the optical waveguide closed-loop resonator is arranged at said plurality of sensor elements and associated with each of the individual sensor elements of the plurality of sensor elements such that a resonance frequency of the optical waveguide closed-loop resonator is shifted due to the affected physical properties of all individual sensor elements of the plurality of sensor elements.

Abstract: A method for manufacturing of a waveguide for guiding an electro-magnetic wave comprising: forming a first waveguide layer, a sacrificial layer and a protection layer on a first wafer, patterning to define a pattern of a first waveguide part and a supporting structure in the first waveguide layer; exposing the sacrificial layer on the first waveguide part while the protection layer still covers the sacrificial layer on the supporting structure; removing the sacrificial layer on the first waveguide part; removing the protection layer; bonding a second wafer to the sacrificial layer of the first wafer such that a second waveguide part is supported by the supporting structure and a gap corresponding to the thickness of the sacrificial layer is formed between the first and second waveguide parts.
