A 25-Gb/s Monolithic Optical Transmitter With Micro-Ring Modulator in 130-nm SoI CMOS

An Si photonic transmitter is integrated in a 130-nm silicon-on-insulator complementary metal-oxide-semiconductor technology. A high-speed photonic ring modulator is designed for 25-Gb/s operation with an 8-dB extinction ratio. The ring is driven with a 2.4-Vpp swing using a low-power inverter driver. With a reference receiver, the 25-Gb/s link is measured with a bit error rate (BER) of 10-12. The total transmitter power consumption is 17 mW at 25 Gb/s for an energy efficiency of 680 fJ/b excluding laser and ring tuning power.
