Integrated Optics Theory And Technology Solution Zip May 2026

This "ZIP" gives a quick start to build a 1550 nm modulatable waveguide + ring-resonator filter on SOI.

Design steps (high level):

Expected first-run metrics: insertion loss ~5–8 dB (including grating), extinction ratio >10 dB, modulation BW ~10–20 GHz (depends on doping/RC).
