Compact InP-on-SOI microdisks used as high-speed modulators and photo detectors

We demonstrate for the first time that a single compact, electrically driven indium phosphide based microdisk heterogeneously integrated on a silicon-on-insulator waveguide can be used as both a high-speed modulator and photo detector. We demonstrate high-speed operation up to 10 Gb/s and present bit-error rate results of both operation modes. © 2012 Optical Society of America.
