- We propose and demonstrate a tunable broadband photonic radio frequency (RF) phase shifter based on a silicon microring resonator. This scheme utilizes the thermal nonlinear effect of the silicon microring to change the electrical phase of the RF signal with a wide tuning range. A prototype of the phase shifter is experimentally demonstrated for a 40-GHz signal with a 0-4.6-rad tuning range.

- We experimentally demonstrate 10-Cb/s format conversion from non-return-to-zero (NRZ) to alternate-mark-inversion (AMI) using the linear filtering effect of silicon microring resonator. Our discussion and analysis in simulation further show that a 10-Gb/s AMI signal with good quality can be obtained by a resonator with a notch depth larger than 25 dB when the 3-dB bandwidth is 0.4 nm.

Compact optical temporal differentiator based on silicon microring resonator

Tidskriftsartikel (refereegranskat)abstract
- We propose and experimentally demonstrate a temporal differentiator in optical field based on a silicon microring resonator with a radius of 40 mu m. The microring resonator operates near the critical coupling region, and can take the first order derivative of the optical field. It features compact size thus is suitable for integration with silicon-on-insulator (SOI) based optical and electronic devices. The performance of this optical differentiator is tested using signals with typical shapes such as Gaussian, sinusoidal and square-like pulses at data rates of 10 Gb/s and 5 Gb/s.

Wavelength Conversion in a Silicon Mode-split Micro-ring Resonator with 1G Data Rate
- 2008
-
Konferensbidrag (refereegranskat)abstract
- We experimentally demonstrate the wavelength conversion based on free carrier dispersion effect induced by non-linear absorption in a silicon micro-ring resonator. The pump and signal wavelengths are set by the split resonances spaced by 0.4 nm induced by deformation in the coupling region. The results of 500 Mbps and 1Gbps are presented.
