Overview

Optics and Photonics
We develop and construct advanced microscope systems for rapid and non-invasive characterization of various systems ranging from semiconductor devices to biological systems. We are also interested in the application of recent advances in optical technology to various instrumentation research ventures. In particular, we manipulate the phase, amplitude, and polarization state of light, and use the generated three-dimensional fields for various applications in optical microscopy, ranging from multiple beam optical trapping, micro-fabrication via nonlinear photo-polymerization, complex field coupling to advanced optical waveguides coupling for fiber sensors, among others.

Synchronization
Interacting elements in various systems communicate and exhibit collective behavior for efficient functioning. Our group looks into the adjustment of the rhythms of natural and artificial systems due even if the interaction is weak or even below the detectable threshold. Current research thrusts of the group include noise induced pattern formation, spatial mode, time series analysis, particle tracking, transverse stability and synchronization of spatial modules in semiconductor lasers. Our group also looks into patterns and synchronization in historical records, literature and real signals.
