Monolithically integrated high-speed CMOS photonic transceivers

We demonstrate monolithically integrated 4×10 Gb/s WDM transceivers built in a production 130 nm SOI CMOS process. Only light sources are external to the chip. 40 Gb/s error-free, bidirectional transmission is demonstrated.

A Fully Integrated 4

Optical and electronic building blocks required for DWDM transceivers have been integrated in a 0.13 mum CMOS SOI technology. Using these building blocks, a 4 x 10-Gb/s single-chip DWDM optoelectronic transceiver with 200 GHz channel spacing has been demonstrated. The DWDM transceiver demonstrates an unprecedented level of optoelectronic system integration, bringing all required optical and electronic transceiver functions together on a single SOI substrate. An aggregate data rate of 40 Gb/s was achieved over a single fiber, with a BER of less than 10-12 and a power consumption of 3.5 W.

We have demonstrated a 40-Gb/s optoelectronic transceiver in a quad small form-factor pluggable (QSFP) module. Each module includes a 4xlO-Gb/s, 0.13 μm CMOS silicon-on-insulator integrated optoelectronic transceiver chip co-packaged with a single, externally modulated CW laser.

10-Gb/s DWDM Optoelectronic Transceiver Implemented in a Standard 0.13

We present our approach to a low-cost, highly scalable opto-electronic integration platform based on a commercial CMOS process. In this talk, we detail the performance of the device library elements and highlight performance trade-offs encountered in monolithically integrating optical and electronic circuits. We describe an opto-electronic integrated circuit (OEIC) design toolkit modeled after the standard electronic design flow, which includes automated design rule checking (DRC) and layout-versus-schematic (LVS) checks covering all types of circuit elements. As an example of integration, we detail the design of a multi-channel transceiver chip with 10 Gbps/channel optical data transmission speed and report on its performance.

For the first time we demonstrate a fully self-contained photonic transceiver system on a single die with monolithically integrated Ge photo-detectors. The transceiver allows error-free bidirectional 4times10 Gb/s WDM transmission using a single CMOS die at each end of the link.
