| Popis: | As the diffraction limit is approached, device miniaturization to integrate more functionality per area becomes more and more challenging. Here we propose a novel strategy to increase the functionality-per-area by exploiting the modal properties of a waveguide system. With such approach the design of a mode-multiplexed nanophotonic modulator relying on the mode-selective absorption of a patterned Indium-Tin-Oxide is proposed. Full-wave simulations of a device operating at the telecom wavelength of 1550nm show that two modes can be independently modulated, while maintaining performances in line with conventional single-mode ITO modulators reported in the recent literature. The proposed design principles can pave the way to a novel class of mode-multiplexed compact photonic devices able to effectively multiply the functionality-per-area in integrated photonic systems. |
