Tunable VCSEL driver presented at IEEE Optical Interconnects Conference

Project partner TUD presented another adaptive circuit in 28 nm CMOS technology. In June at IEEE Optical Interconnects Conference, this time an adaptive VCSEL driver is presented which is capable of up to 30 Gb/s with only 1.7 pJ/bit. Successful down-scaling to 15 Gb/s is demonstrated while reducing the power consumption significantly and  maintaining the modulation amplitude.
