Optical microscope image of the device, which consists of an 80 ?m radius ring resonator coupled to an MZI. The ring has a p-i-n diode integrated around it. Waveguide cross sections at various parts of the device are shown.
(a) Architecture of the WDM Optical Network Unit (ONU). (b) Configuration of the individual colorless ONU. (c) Transmission spectra of the AWG, microring demultiplexer (Demux), and the microring modulator (Si Mod), respectively.
Michal Lipson does groundbreaking research on nanophotonics—“optics on a very, very small scale." In this interview for Fusion’s “Genius” series she explains how nanophotonics could revolutionize the way computers work.
