    <title language="eng">A Far-Field Interpretation of the Optical Chirality</title>
    <abstract language="eng">A chiral structure is not super-imposable with its mirror image. Most commonly found in  organic  molecules, chirality  can  also  occur  in  other  systems,  such  as  electromagnetic fields, where circularly    polarized    light    is    the    most widespread example. Chiral electromagnetic  fields  can  be  a  useful  tool  for  biosensing  applications.  In  particular,  it  has been  shown  that  chiral  plasmonic  nanostructures  have  the  ability  to  produce  strongly enhanced   chiral   near-fields. Recently, our   group   has   developed   chiral   plasmonic nanopyramids, which have the ability to focus chiral near-fields at their tip. This could enable chiral sensing at the single-molecule level. Chiral near-fields can be characterized in terms of the “optical chirality density”. This time-even and parity-odd pseudoscalar was first derived by Lipkin and was found to follow a conservation  law  analogous  to  the  energy  conservation  of electromagnetic  fields.  More recently, Tang and Cohen identified the physical meaning of the “optical chirality density” as the degree of asymmetry in the excitation rate of a chiral molecule. However, how this near-field  interpretation  of  the  optical  chirality  could  translate  into  the  far-field  is  not  well understood. Here, we formulate  a  far-field  interpretation  by  investigating the  conservation  law  for optical chirality in matter, and performing time-averaging in analogy to Poynting’s Theorem. In  parallel  to extinction  energy,  we  define  the  “global  chirality”  as  the  sum  of  chirality dissipation  within a  material and  the  chirality  flux  leaving  the  system. With  finite-element simulations, we place a dipole source at locations of enhanced local chirality and investigate the  global  chirality  and  ellipticity  of  emitted  light  in  the  far-field. Interestingly,  we  find  that lossy materials with a complex dielectric function have the ability to generate global chirality when excited by achiral light. In particular, chiral plasmonic nanostructures  are  found  to  act as effective global chirality generators. The global interpretation of optical chirality provides a useful  tool  for  biosensing  applications  with  chiral  plasmonic  nanostructures,  where  the detection is routinely performed in the far-field.</abstract>
