Ultrafast Excitonic Transitions in Enantiopure and Racemic Squaraine Thin Films
Aggregate, Volume 6, Issue 3, March 2025.Ultrafast optical excitation of both J‐ and H‐like bands in enantiopure ProSQ‐C16 thin films leads to highly similar spectral and dynamic responses, suggesting that a single aggregate type is responsible for the excitonic properties such as the giant circular dichroism reported previously.

Mueller polarimetry of discontinuous gold films
Semiconductor Physics, Quantum Electronics & Optoelectronics, 2019 The problem of controlling morphology of discontinuous gold films by the method of optical angular Mueller-polarimetry is considered. A set of the samples of such films with different amounts of sputtered metal has been fabricated and studied.

Mueller matrix polarimetry for differentiating characteristic features of cancerous tissues
Journal of Biomedical Optics, 2014 Polarization measurements allow one to enhance the imaging contrast of superficial tissues and obtain new polarization sensitive parameters for better descriptions of the micro- and macro- structural and optical properties of complex tissues. Since the majority of cancers originate in the epithelial layer, probing the morphological and pathological ...
