I am very interested in the fact that this SOI claims "Ultra-lower power consumption with 0.4 volt operation".

PET & POET ofer 0.3-0.5V operation vs 0.8V in Silicon CMOS

This is identical to what G.T. wrote about back in 2011, and aligns to the POET CP:
"By carefully optimizing waveguide parameters and subsequent bend efficiency, a resonator with a waveguide width of 1 µm, a gap of 0.25 µm between the waveguide and the resonator, and a rectangular resonator region of 3 × 13 µm shows a normalized output power of 0.7 and 0.04 for input wavelengths of 982.8 nm (resonant) and 985.2 nm (nonresonant), for an extinction ratio of 12.4 dB. Power consumed by the device with a bias voltage of 0.4 V is less than 1 mW."
