RF photonic frontend on a chip

We present the concept, design, fabrication and preliminary measurement results of a RF photonic fronted on a photonic IC chip. The RF photonic frontend employs linear optical phase modulation and linear phase demodulation by an ACP-OPLL. The link achieves frequency down-conversion by optical sampling. The preliminary results demonstrated down conversion SFDR of 108.1dBHZ
