Low-voltage 60Gb/s NRZ and 100Gb/s PAM4 O-band silicon ring modulator Universiteit Gent
We demonstrate 60Gb/s NRZ and 100Gb/s PAM4 data modulation with an O- band silicon ring modulator with only 1.6Vpp and 2.5Vpp drive swing respectively, leveraging the large modulation efficiency (55pm/V) and electro- optical bandwidth (35GHz) realized by an optimized vertical PN diode phase shifter design.
