Abstract
Enhancement of radiative coupling efficiency between out-of-plane excitonic emitters in an indium selenide (InSe) film and an integrated waveguide formed by silicon (Si) Mie-resonant nanodisks is experimentally studied. Photoluminescence power at the resonant waveguide output is increased by~2.5 times at 950~nm in comparison with the case of a conventional rib waveguide of the same geometrical parameters due to the efficient excitation of Mie-type magnetic dipole resonances in individual nanoparticles. These results show inspiring possibilities for creating new on-chip light emitters for various integrated photonics applications.
