Spectral shaper for radio frequency waveform generation on a silicon chip
Abstract
A novel on-chip arbitrary radio frequency waveform generator based on thermally tunable microring resonators is presented. The efficacy of this device, even with eight line resonant tuning, is found to be 18dB in the RF spectrum with only 3% thermal crosstalk during tuning. This low footprint device, due to high index silicon, is meant to be a replacement for its bulk optical counterpart, where wavelength-time mapping have generated RF response at both 40GHz and potentially into the THz regime. In addition, low loss chip has been designed for insertion loss improvement from 29 to 12dB. Design, fabrication and simulation details are provided to illustrate the workings of the aforementioned device.
