PMID: 26207470
Phys Rev Lett. 2015 Jul 10;115(2):023902. doi: 10.1103/PhysRevLett.115.023902. Epub 2015 Jul 08.

We combine high-finesse optical resonators and spatial-spectral interferometry to a highly phase-sensitive investigation technique for nonlinear light-matter interactions. We experimentally validate an ab initio model for the nonlinear response of a resonator housing a gas target, permitting the global...

PMID: 25836788
Opt Express. 2015 Mar 09;23(5):5565-70. doi: 10.1364/OE.23.005565.

We developed a new method aimed at designing short-pass filters, long-pass filters and filters blocking sidebands of Fabry-Perot bandpasses. The method is an automated version of a non-straightforward empirical approach invented as a result of many years' experience in...

Polymeric micelles as carriers of diagnostic agents.

Advanced drug delivery reviews

Adv Drug Deliv Rev. 1999 Apr 05;37(1):81-88. doi: 10.1016/s0169-409x(98)00100-8.

This review deals with diagnostic applications of polymeric micelles composed of amphiphilic block-copolymers. In aqueous solutions these polymers spontaneously form particles with diameter 20-100 nm. A variety of diagnostic moieties can be incorporated covalently or non-covalently into the particulates...

Optical coating design approaches based on the needle optimization technique.

Applied optics

PMID: 17279158
Appl Opt. 2007 Feb 10;46(5):704-10. doi: 10.1364/ao.46.000704.

Design approaches for optical thin films that recognize the key role of a design's total optical thickness are presented. These approaches are based primarily on the needle optimization technique but also utilize other optimization procedures. Using the described design...

Appl Opt. 2009 Feb 10;48(5):949-56. doi: 10.1364/ao.48.000949.

A new model for the determination of group delay (GD) and GD dispersion of dispersive mirrors is presented. The algorithm based on this model enables one to process interferometric data provided by a white-light interferometer and to obtain GD...

Computational experiments on optical coating production using monochromatic monitoring strategy aimed at eliminating a cumulative effect of thickness errors.

Computational manufacturing of optical coatings is a research area that can be placed between theoretical designing and practical manufacturing in the same way that computational physics can be placed between theoretical and experimental physics. Investigations in this area have...

Reverse engineering of multilayer coatings for ultrafast laser applications.

PMID: 24514202
Appl Opt. 2014 Feb 01;53(4):A114-20. doi: 10.1364/AO.53.00A114.

We propose a reliable reverse engineering approach for a postproduction characterization of complicated optical coatings for ultrafast laser applications. We perform the postproduction characterization on the basis of in situ broadband monitoring data and validate the results using ex...
