Resumen
Depressed cladding optical waveguides have been fabricated in a
zinc sulfide (ZnS) crystal by femtosecond laser inscription. The structures
support single- or multi-mode guidance at the mid-infrared wavelength of
~4 μm. The two-dimensional refractive index profiles of the single-mode
waveguides have been reconstructed, and the modal profiles of TE and TM
modes were calculated numerically, that show very good agreement with
the measured near-field modal profiles. The minimum propagation losses of
the multimode cladding waveguides at 4 μm were ~1.1 dB/cm for the TE
polarization and ~1.3 dB/cm for the TM polarization.
