|Abstract:||Si modulators and Ge photodetectors are monolithically integrated on Si-on-insulator. The carrier-depletion-type Si modulators achieved high modulation efficiency and speed (VπLπ = 2.56 Vcm, 10 Gb/s). Low-voltage operation (VRF = 1Vpp) was also demonstrated. Introducing a low-thermal-budget postepitaxy anneal improves the performance of the Ge photodetectors, thus resulting in significantly improved dark current. The responsivity and speed in the low-voltage regime are also enhanced, which enhances low-voltage or even short-circuit (VBias = 0 V) operation. © 2006 IEEE.|
