Silicon photonics has proved itself to be the most promising platform for the next generation photonic technologies and products, ranging from AI accelerators and quantum photonic integrated circuits to consumer healthcare. Conventionally, various sub-micron waveguide platforms are in use, having high propagation and coupling loss. In contrast, VTT’s 3-µm thick-SOI platform offers a more promising alternative, owing to its ultra-low propagation (3 dB/m), SMF coupling loss, and negligible polarization sensitivity. On this platform, we report a proof-of-principle demonstration of a high-speed electro-optic phase modulator based on electro-optic Kerr effect (or DC Kerr effect) as well as its wafer-scale manufacturability.
