On-chip Silicon photonics assisted frequency doubling and pulse generation

摘要

We present a Silicon photonics assisted RF signal processing, in particular, frequency doubling and RF pulse generation. We demonstrate frequency doubling till 10 GHz using silicon PN ring resonator and we present a detailed study on the effect of carrier offset on the power and linewidth of the up-converted RF signal by increasing the Local Oscillator(LO) frequency. We also demonstrate a photonics approach of pulse generation using an on-chip Silicon PN Mach-Zehnder modulator, where RF-signal frequency between 1-12 GHz could be fed and pulsed at various rates from 100-0.1 millisecond.
