Query: Mechanical and Optical Characterization of a Suspended Core Fiber
  Exhibiting Fundamental-Mode Cutoff Wavelength in Presence of Nanoscale Air
  Holes in the Core Region   In this work, mechanical and optical characterization of a new type of
suspended core fiber (SCF) has been performed. The proposed SCF along with
additional central air holes exhibits an unusual property of fundamental mode
cutoff at short wavelengths. Two variants (single hole and double hole) of
design under two different fiber platforms (SiO2 and As2Se3) have been
considered to develop better insight into the mechanical and optical properties
of the structure deploying plane strain and full vector eigen analysis,
respectively. Dependence of thermal stress likely to be present in such
nanostructured fibers on fiber materials and geometries are thoroughly studied.
A relation between the cutoff condition and geometrical parameters of the
design has been obtained with reference to characteristic decay length which
nullifies the possibility of any numerical artifact. In addition, improvement
of fiber birefringence and evanescence sensing capability due to the presence
of such air holes in the guided region has been theoretically demonstrated.
Effects of such air holes on fiber properties like GVD and mode mismatch are
also studied with a relation to power confinement inside such nano scale
regions.
