Konstantin Vodopyanov MirCombs Research Group, CREOL – the College of Optics and Photonics, Univ. Cent. Florida

Our group develops groundbreaking techniques for producing mid-IR and terahertz coherent radiation and explores their diverse applications. The areas of research embrace generation of ultra-broadband frequency combs in the mid-IR and THz and study of their coherence properties, Fourier-domain mid-IR spectroscopy including dual-comb spectroscopy, ultrasensitive molecular detection, spectroscopic study of dynamic processes (e.g. combustion), and nano-IR spectroscopy. We also explore supercontinuum generation in fibers and waveguides, photonic THz wave generation, THz imaging via up-conversion, as well as applications of lasers and frequency combs for bio-medical research.

Research Areas

Ultra-broadband frequency combs  Optical parametric oscillators (OPOs) have long been recognized as a versatile means of producing optical output in important spectral regions unreachable by laser sources. The mid-IR (> 2.5 µm) is one such region …   see more

Dual-comb MIR spectroscopy Mid-infrared spectroscopy offers unparalleled sensitivity for the detection of trace gases, solids and liquids, based on the existence of strongest telltale vibrational bands in the 3-12 µm …  see more


Photonic THz wave generation   Photonic generation of THz waves via frequency down conversion in electro-optic crystals is an attractive (thanks to the progress in developing compact near-IR optical sources) but inefficientsee more


NANO IR spectroscopy  The ability to identify material under the tip of an atomic force microscope (AFM) is one of the Holy Grails of scanning probe microscopy. While AFM can measure mechanical, electrical, magnetic and thermal properties  ….  see more
