Professor Minnich researches the physics and engineering of nanoscale heat transport. Nanostructured materials have novel thermal properties with applications in energy such as for thermoelectric materials, which convert heat directly to electricity. Minnich uses experimental techniques, including ultrafast optical experiments, to study transport at the length and time scales of the energy carriers themselves. These experiments measure properties of the energy carriers that are lost at macroscopic scales, allowing for a more complete understanding of nanoscale transport physics. Minnich also uses these results to design novel materials and thermal devices, such as more efficient thermoelectric materials and devices for thermal energy storage.

Professor of Applied Physics, Aeronautics, and Mechanical Engineering

The Laboratory of Interfacial and Small Scale Transport {LIS2T} in the Department of Applied Physics and Materials Science at the California Institute of Technology specializes in both fundamental analysis and engineering design of micro/nanoscale fluidic systems. Of particular interest are small scale systems  dominated by large surface forces due to patterned capillary, van der Waals, Maxwell, thermocapillary and Marangoni fields. Theoretical analysis, numerical simulations (both continuum and molecular scale) and experimentation are all used to develop fundamental physical insight as well as robust design principles for application driven projects. Group focus is on formation, propagation, stability, coupling and control of nonlinear wave phenomena at the micro/nanoscale which induces rapid transport of mass, momentum and heat at moving interfaces. Systems of current theoretical interest include cusp formation in thermally and electrically driven thin films for super anti-reflecting coatings and space micropropulsion devices; nanofluidic phenomena involving Kapitza thermal jumps, layering transitions and thermal rectification in nanoscale devices; spatio-temporal parametric resonance and array formations in thin polymeric films exposed to large thermocapillary and Maxwell patterned fields; Lyapunov, modal and transient growth stability analyses of non-normal systems at zero Reynolds number; capillary and field enhanced propellant management systems for space micropropulsion applications; and solution of inverse problems for 3D lithographic patterning of nanofilms. Systems of current experimental interest include non-contact lithography of 3D micro-optical structures by patterned external fields; Marangoni wave phenomena and fractal wavefronts in biophysical systems; influence of layering transitions on slip behavior in nanoscale films; and optical wave propagation in structured polymeric waveguides.

Kerry Vahala has pioneered nonlinear optics in high-Q optical micro resonators. His research group has launched many of the areas of study in this field and invented optical resonators that hold the record for highest optical Q on a semiconductor chip.  Vahala has applied these devices to a wide range of nonlinear phenomena and applications. This includes the first demonstration of parametric oscillation and cascaded four-wave mixing in a micro cavity - the central regeneration mechanisms for frequency micro combs; electro-optical frequency division - used in the most stable commercial K-band oscillators;  and the first observation of dynamic back action in cavity optomechanical systems. His micro-resonator devices are used at the National Institute of Standards and Technology (NIST) in chip-based optical clocks and frequency synthesizers. They have also been used at the Keck II observatory in Hawaii as miniature astrocombs in the search for exoplanets. Vahala's current research is focused on the application of high-Q optical micro resonators to miniature precision metrology systems as well as monolithic optical gyroscopes. Professor Vahala was also involved in the early effort to develop quantum-well lasers for optical communications. That work formed the basis for nearly all of today’s high-speed semiconductor laser design for lightwave high-speed telecommunications, particularly in the metropolitan and local-area arena.
