Inverting and non-inverting operation of InP microdisc modulators
Abstract
Reported is the inverting and non-inverting operation of indium phosphide (InP)-based microdisc modulators heterogeneously integrated on a silicon-on-insulator waveguide. The light transmitted through the waveguide can be modulated in an inverting and non-inverting manner depending on the bias conditions. Static extinction ratios and dynamic operation of the device up to 2.5Gbit/s are demonstrated. Clean open eyes with extinction ratios better than 6dB are shown and operation with a bit error rate below 1×10 -10 is demonstrated at 1.0Gbit/s for both operation modes with a bias of only 1 Vpp. © 2012 The Institution of Engineering and Technology.
