Table 2 Comparison between the PnIC and the PIC
From: Phononic integrated circuitry and spin–orbit interaction of phonons
PnIC | PIC | |
|---|---|---|
Input/Output | Interdigital transducer | Grating coupler |
External ports | RF cable | Fiber |
Interconnection | Phononic waveguide | Photonic waveguide |
Velocity | 4000 m s−1 | 1.3 × 108 m s−1 (in GaN) |
Modes | Rayleigh/Love-like | Quasi-TE/TM |
