- *Abstract
-
Cornellresearchers have demonstrated optical filters and resonators which can be tunedover a very broad range of wavelengths using a few mW of optical control signalpower.
GHz modulation in a 2.5 μm radius silicon micro-ring was demonstrated, with only 150 mV peak-peak drive voltage and an electro-optic modal volume of only 2 μm3. These results correspond to the smallest known electro-optic switching energy and modulation voltage swing for a silicon electro-optic device. The Cornell approach lays the groundwork for a new class of high-speed, low-voltage modulators, enabling seamless integration of nanophotonics with low-voltage digital CMOS nanoelectronics.
