Micro-transfer Printed Membrane Laser and Electroabsorption Modulator on Si waveguide Integrated with Polymer Spot-size Converter

We demonstrate micro-transfer printing for integrating multiple III-V devices with different bandgaps on Si platforms. Membrane DFB lasers and EA modulators are fabricated on Si waveguides with polymer-based spot-size converters, modulating at $128 \mathrm{Gbit} / \mathrm{s}$-NRZ signal.
