A Hybrid Electrooptic Microring Resonator-Based 1 x 4 x 1 ROADM for Wafer Scale Optical Interconnects


Pairing high-quality factor (Q) silicon-on-insulator microring resonators with rapidly tunable organic electrooptic claddings has allowed the first demonstration of a silicon-organic hybrid electrooptic reconfigurable optical add/drop multiplexer (ROADM). A coplanar electrode geometry provides up to 0.36 GHz/V of electrooptic voltage tuning for each channel, corresponding to an electrooptic coefficient of r_(33) = 64 pm/V at wavelengths around 1550 nm. Individual ring resonator devices have 40-µm ring radii, 2.7-nm free spectral range, and tuning ranges of 180 GHz. The 1 × 4 × 1 ROADM has a footprint of less than 1 mm^2 and has been shown to reconfigure in less than a microsecond.
