Schematic structures of devices and cavities.
(a) Here we investigate performance scaling of four photonic devices, namely a laser source, an electro-optic modulator, a photodetector, and an all-optical nonlinearity-based switch (the latter is not shown). The physical device volume is given by the device geometry. (b) Here we utilize three device-underlying cavity types; namely a ring resonator (RR) cavity with the waveguide width, w, and the ring radius, r; a Fabry-Pérot (FP) cavity comprised of a dielectric material sandwiched by a pair of highly reflecting metal mirrors with the reflectivity of R1 and R2; and a plasmon cavity formed by metal nanoparticle (MNP) embedded in a dielectric, and a is the radius of metal nanoparticle. d represents the normal distance for the dipole position from the metal particle surface as is equal to 10 nm. The scaling parameters are r, for the RR, l for the FP, and a for the MNP cavity, respectively.
