PY - 2012 SN - 1862-6254 UR - http://hdl.handle.net/10366/146870 AB - We report on the fabrication of nonlinear KTiOPO4 (KTP) cladding waveguides by using femtosecond-laser direct inscription. The produced guiding structures with a circular cross section of ∼100 μm diameter support good light confinement both for the...
