Systematic or multiple reproduction or distribution to multiple locations via electronic or other means is prohibited and is subject to penalties under law.[EN] A novel ultracompact electro-optic phase modulator based on a single 9 ¥ìm-diameter III-V microdisk resonator heterogeneously integrated on and coupled to a nanophotonic waveguide is presented. Modulation is enabled by effective index modification through carrier injection. Proof-of-concept implementation involving binary phase shift keying modulation format is assembled. A power imbalance of ¡-0.6  dB between both symbols and a modulation rate up to 1.8 Gbps are demonstrated without using any special driving technique.The authors gratefully acknowledge the financial support given by the European Seventh Framework Programme through the projects GOSPEL, WADIMOS, and HISTORIC; the Generalitat Valenciana through the Microwave Photonics Excellency Award programme GVA PROMETEO 2008/092; and also the Plan Nacional I+D TEC2011-29120-C05-05 and TEC2008-06145.Lloret Soler, JA.; Kumar, R.; Sales Maicas, S.; Ramos Pascual, F.; Morthier, G.; Mechet, P.; Spuesens, T....
