M. J. Therien, PI

Establish nanoscale architectures that carry out electrical-to-optical signal transduction, optical beam steering, optical phase control, and optical limiting functions.

Chromophore engineering (Therien) and de novo protein design (Saven, DeGrado) are exploited to develop nanoscale analogues (Blasie, Bonnell, Johnson) of macro-scale electrooptic devices such as frequency doublers, electrooptic modulators, waveguide switches, and polarization transformers.

Demonstrated de novo design of a four-helix bundle protein that selectively binds a non-biological cofactor defines a path to developing well-defined nanoscale materials that have unique electrooptic functionality.
