LIGO: Laser Interferometer Gravitational wave Observatory consists of two detectors (one in Livingston, LA and the other in Hanford, WA) operating in coincidence with the goal to search and detect gravitational waves from compact binary stars, black holes, supernovae, and other sources.
I have been involved with LIGO project since its initial funding by the NSF in 1995.
At UTB, we conduct experiments with lasers and optics in support of LIGO detector instrument science.
We study laser frequency stabilization, laser ring resonators, Pound-Drever-Hall locking, and other high-precision interferometric techniques.
I am also interested in searches for short-duration (burst) signals with multiple detectors, particularly in mathematical problems associated with ill-conditioned detector response matrix and the methods to overcome this difficulty, e.g. Tikhonov regularization.
Photonic Crystals: Major efforts in science and technology today are focused on understanding of how to control, confine and route light in integrated micro-photonic circuits and devices.
Photonic crystals are man-made materials with periodic structure forming a lattice with spacing tuned to the wavelength of visible or infra-red light.
We are studying synthetic opals (FCC photonic crystals) and silicon nano-patterned membrane reflectors.
Computational Electromagnetics: This is a rather new field of research. Its goal is to provide very accurate description of how electromagnetic waves propagate in metamaterials, photonic crystals, micro-resonators, integrated silicon photonic circuits and other devices.
The main tool is the Finite-Difference Time-Domain (FDTD) simulation which is typically run on a large-scale computer architecture.
We are running FDTD simulations (FullWave from RSoft and MEEP from MIT) to study photonic crystals, ring resonators, waveguides and nanocavities.
