  • Abstract
    A single-step technique for defining 2D channel waveguide structures with internal Bragg gratings in photosensitive germanosilica-on-silicon using two interfering focused UV beams is presented. Through software control, grating detuning across the S-, C-, and L-wavelength bands is also demonstrated.
