High-speed performance of a TDFA-band micro-ring resonator modulator and detector.

We demonstrate a silicon-on-insulator micro-ring resonator (MRR) modulator and defect-mediated (DM) detector operating at a wavelength near 2 µm for use in the thulium doped fiber amplifier wavelength band. The MRR modulator was critically coupled with an unbiased notch-depth of 20 dB and Q-factor of 4700. The resonance shift under reverse bias was 23 pm/V with a calculated V_πL_π of 2.2 to 2.6 V·cm from -1 to -8 V, respectively. Simulations are …
