Transmitters and Receivers

Research

In addition to the intensity, information can be encoded on the phase, frequency, and polarization of an electromagnetic wave to carry information. Advanced modulation formats utilize a combination of these properties to increase the data carrying capacity of transmission channels. Corresponding transmitters and receivers require many functions such as intensity modulators, phase modulators, phase shifters,…

On-Chip and Short-Reach Optical Interconnects

Research

As the demand for data continues to increase, optical interconnects are becoming more attractive for on-chip and short-reach data links. Our group has been developing technologies for optical interconnects to and inside data centers, and we have also been investigating the design and architecture of optically interconnected manycore processor systems. Important technologies for these applications…
