A waveguide for guiding an electro-magnetic wave, a photonic integrated circuit component, a sensor and an actuator KU Leuven
A waveguide (100) for guiding an electro-magnetic wave comprises: a first waveguide part (102);and a second waveguide part (104); wherein the first waveguide part (102) 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 (104) 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 (106) in a second direction (Z) perpendicular to the first and second planes in which the ...
