In this study, the authors have proposed, analysed and simulated the performances of three devices of L-shaped filter, mode separator and power divider based on plasmonic waveguides with nanocavity resonators. The proposed L-shaped filter provides a useful component for bent structures. The mode separator can prevent some specific wavelengths to be transmitted to the output, and the power divider offers a symmetric power splitting filter-based structure. The finite difference time domain method has been adopted to yield the simulation results. The proposed devices are appropriate for all optical telecommunication systems and networks. Owing to the structures’ dimensions in the nanometre range, the devices can be employed in photonic integrated circuits.
