A novel optical vector network analyzer (OVNA) system based on silicon-on-insulator integrated optical bandpass filter is presented, which improves measurement accuracy in both magnitude and phase responses due to higher resolution and sideband suppression ratio offered by the new OVNA system.
We propose a novel RF photonic modulator that Is based on a coupled dual-cavity resonator. We show that such a coupled cavity system can perform efficient RF-to-optical signal conversion, in one example with more than 30 dB improvement over a single-cavity resonant modulator.
A photonic microwave image-reject and singlesideband mixer is proposed based on a dual-polarization dualdrive Mach-Zehnder modulator. Results show that the image- and sideband-reject ratios of the proposed IRM and SSM are larger than 60 and 30 dB, respectively, and the LO leakage is largely suppressed.
We use the RF analogue of electromagnetically induced transparency (EIT) to demonstrate a high resolution (22 MHz) integrated RF-photonic filter with an enhanced suppression (>30 dB) and an order-of-magnitude amplification in the group delay response. We implement the filter using low-power on-chip stimulated Brillouin scattering.
