CMOS Electronic Circuits in Standard Silicon Photonics

We present the integration of CMOS electronic circuits into a standard Silicon Photonics platform. The designed electronics, fabricated without modifying the fabrication process employed by commercial foundries, targets the detection and processing of electrical signals directly on the photonic chip. First, we show the operation of multiplexers and sample&hold circuits for sequentially controlling large-scale photonic systems with few electrical signals. Then, we present the integration of a transimpedance amplifier for monitoring light signals down to -40 dBm with a frequency up to 2 MHz. These examples represent a first step towards complex electronic processing and elaboration in standard Silicon Photonics.
