We have developed multiple spectroscopic coherence imaging methods to assess pre-cancerous states by isolating scattering signatures from specific tissue locations. We describe the basis, validation and development of the approaches and recent clinical results.

Fiber-optic dispersion-managed solitons can form stable molecules. Systematically mapping out parameter space using a flexible pulse shaper, we investigate the binding mechanism and confirm predictions. Phenomena off equilibrium are also described and explained.

Optical resonators with Q values of nearly 1 billion are demonstrated, the highest for any chip-based devices. Fabrication uses only standard semiconductor processes, enabling precise size control and access to microwave-rate free-spectral-range operation.

We compensate for the losses in 3D arrays of nanoshells through quantum dots embedded in the nanoshells' cores, to achieve ε-near-zero metamaterials at optical frequencies. Results show loss-compensation or gain-capability in a narrow frequency band.
