The as-deposited films were photosensitive at wavelengths close to the band edge (∼520 nm), and waveguides could be directly patterned into theKeywords: Four wave mixing; Neodymium lasers; Photochromism; Photosensitivity; Pulsed laser deposition; Q switched lasers; Rapid thermal annealing; Refractive index; Thin films; Waveguides; Wavelength; Arsenic compounds20032015-12-12
