세미나 제목 : Strained SiGe Optical Modulator for Electronic-Photonic Integrated Circuit

발표초록 : There have been great achievements in the development of Si-based optical modulators, which are a key component for high-speed and low-power optical interconnects, particularly for data center networks. However, a carrier-depletion Si modulator requires a relatively long phase shifter or a high driving voltage owing to its low modulation efficiency caused by the weak plasma dispersion effect in Si. This is unfavorable for large-scale integration in terms of a small footprint, low driving voltage, and low power consumption. To improve in the modulation efficiency for the large-scale integration, we have proposed strained SiGe technology for modulators, variable optical attenuators. In this talk, we will briefly overview the basic concept of strained SiGe technology and some recent results and progress for SiGe-based optical modulator/attenuator.
