NRZ and PAM-4 Direct Modulation of <tex>$1.3\ \mu\mathrm{m}$</tex> Quantum Dot Lasers Grown Directly on On-Axis (001) Si
Description
We demonstrate high-speed direct-modulation of InAs/InGaAs quantum dot lasers grown on on-axis (001) silicon. The devices exhibited a 12.5 Gbit/s NRZ operation and a 25 Gbit/s PAM-4 operation confirmed from eye diagrams and BER measurements.
