We present a new bulk-Si optical platform for the optical interfaces toward DRAM integration with localized SOI structure and SPE. The demonstration shows that the waveguide and coupling loss are −0.61dB/mm and −2.6dB, respectively.

We report a nano-sized silicon waveguide by forming partial silicon-on-insulator structure with SPE on bulk silicon substrate. The propagation loss is as low as 6.1 dB/cm, which is close to that of silicon-on-insulator based waveguide.
