Ultrafast Laser Fabrication of Low-Loss Waveguides in Chalcogenide Glass with 0.65 dB/cm Loss

Not Accessible

Your library or personal account may give you access

Abstract

We present 0.65-dB/cm loss symmetric waveguides fabricated in Gallium Lanthanum Sulfide glasses using spatial and temporal shaped ultrafast laser pulses. Micro-Raman analysis was used to correlate optical loss versus laser-induced lattice damages.
