Optical Chirality Enhancement in Twisted Arrays of Plasmonic Nano-rods
An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...
متن کاملOptical Trapping
An optical trap or “optical tweezers” is a device which can apply and measure piconewton sized forces on micron sized dielectric objects under a microscope using a highly focused light beam. It allows very detailed manipulations and measurements of several interesting systems in the fields of molecular and cell biology and thus acts as a major tool in biophysics. They are used in biological exp...
متن کاملCharacterizing optical chirality
We examine the recently introduced measure of chirality of a monochromatic optical field [Y. Tang and A. E. Cohen, Phys. Rev. Lett. 104, 163901 (2010)] using the momentum (plane-wave) representation and helicity basis. Our analysis clarifies the physical meaning of the measure of chirality and unveils its close relation to the polarization helicity, spin angular momentum, energy density, and Po...

متن کاملLight with enhanced optical chirality.
Tang and Cohen [Phys. Rev. Lett.104, 163901 (2010)] recently demonstrated a scheme to enhance the chiral response of molecules, which relies on the use of circularly polarized light in a standing wave configuration. Here we show a new type of light that possesses orbital angular momentum and enhanced chiral response. In the locations where the beams show enhanced optical chirality, only the lon...
