The insertion of mobile ions and coupled changes of electron concentration are exploited to induce a non-volatile and reversible change of the optical properties of mixed ionic and electronic conductors (MIECs). The physical mechanisms responsible for the change of the real and imaginary part of the MIECs' refractive index upon ion-intercalation are extensively investigated in the visible and near-IR...
The CLIPP technology enabling non-invasive on-chip monitoring of the light intensity is exploited to realize feedback controlled schemes for the tuning, switching, and locking of photonic integrated circuits. Applications to photonic architectures based on silicon photonic microring resonators and Mach-Zehnder Interferometers are presented.
A high sensitivity in-band OSNR monitor system integrated on SOI platform is presented. The device exploits a narrow-band microring resonator to select the portion of the channel spectrum that is most sensitive to OSNR variations, and performs an autocorrelation measurement using a Mach-Zehnder interferometer. The proposed scheme allows in-line OSNR monitoring from 8 dB to 28 dB, with 0.2 dB accuracy.
In this paper, we report a direct comparison between coupled resonator optical waveguides (CROWs) and photonic crystal waveguides (PhCWs), which have both been exploited as tunable delay lines. The two structures were fabricated on the same silicon-on-insulator (SOI) technological platform, with the same fabrication facilities and evaluated under the same signal bit-rate conditions. We compare the...
