Wang S, Lipchus E, Gharbi M, Yelleswarapu C
Micromachines (Basel)
. 2023 Dec;
14(12).
PMID: 38138375
We investigate the plasmon coupling of gold nanoparticle (AuNP) dimers dispersed in a nematic liquid crystal matrix using the polarization z-scan technique. Our experimental setup includes the precise control of...

Nanotechnology
. 2023 Jun;
34(36).
PMID: 37285825
We report structural and nonlinear optical properties of 20 nm gold (Au) nanoparticles (NPs) that are dispersed in planar degenerate (non-oriented) and planar oriented nematic liquid crystals (LCs) (4'-Pentyl-4-biphenylcarbonitrile-5CB). Taking...

Li Y, Petrovic L, La J, Celli J, Yelleswarapu C
J Biomed Opt
. 2014 Nov;
19(11):116001.
PMID: 25364948
We report the use of digital holographic microscopy (DHM) as a viable microscopy approach for quantitative, nondestructive longitudinal imaging of in vitro three-dimensional (3-D) tumor models. Following established methods, we...

Das B, Yelleswarapu C, Rao D
Opt Commun
. 2013 Mar;
285(21-22):4262-4267.
PMID: 23471012
We present a robust encryption method for the encoding of 2D/3D objects using digital holography and virtual optics. Using our recently developed dual-plane in-line digital holography technique, two in-line digital...

Das B, Yelleswarapu C, Rao D
Opt Commun
. 2012 Oct;
285(24):4954-5960.
PMID: 23109732
We present a digital holography microscopy technique based on parallel-quadrature phase-shifting method. Two π/2 phase-shifted holograms are recorded simultaneously using polarization phase-shifting principle, slightly off-axis recording geometry, and two identical...

Das B, Yelleswarapu C, Rao D
Appl Opt
. 2012 Mar;
51(9):1387-95.
PMID: 22441487
We present detailed theoretical evaluation and thorough experimental investigation of quantitative phase imaging using our previously demonstrated dual-plane in-line digital holographic microscopy technique [Opt. Lett. 35, 3426 (2010)]. This evaluation...

Opt Lett
. 2010 Oct;
35(20):3426-8.
PMID: 20967088
We report a dual plane in-line digital holographic microscopy technique that exploits the method of subtraction of average intensity of the entire hologram to suppress the zero-order diffracted wave. Two...

Opt Express
. 2010 Jul;
18(9):9020-5.
PMID: 20588748
We report a novel photoacoustic Z-scan (PAZ-scan) technique that combines the advantages offered by the conventional Z-scan method and the sensitivity of the photoacoustic detection. The sample is scanned through...
