Channel waveguides incorporating photo-imprinted Bragg gratings were produced in germano-borosilicate glass layers fabricated by flame hydrolysis deposition, through single- and double-step exposure direct writing processes with UV laser irradiation.

The aim of this study was to develop and optimise a process to etch deep, high aspect ratio microstructures in glasses. To this end, we examined the use of flame hydrolysis deposition (FHD) to form integrated lab-on-a-chip structures involving silica

Fluorescence lifetimes and scatter losses for Er 3+ doped, silica waveguides formed by aerosol doping and flame hydrolysis deposition are reported. The fast decay component and out of plane scatter decreased markedly with optimisation of the depositi

Results on rare-earth-doped lasers and amplifiers in planar silica waveguides fabricated by flame hydrolysis deposition (FHD) and reactive ion etching (RIE) are presented. The authors review their results on the optimisation of doping levels, co-dopa

A neodymium-doped glass waveguide laser based on a new structure employing two core layers is reported. This double-layer structure allows a photosensitive layer to be integrated with an efficient gain layer. Singlemode operation was obtained with a

Permanent photo induced refractive index changes by means of UV exposure have been used for laser trimming, fabrication of Bragg gratings [1] and direct writing of channel waveguides [2]. Direct writing is particularly attractive since it allows two-

We present a single-step technique for defining 2-dimensional integrated channel waveguide structures with internal Bragg gratings in photosensitive germanosilica-on-silicon substrates using two interfering focussed UV beams. Detailed device analysis

We present a single-step technique for defining channel waveguides with internal Bragg gratings in photosensitive germanosilica-on-silicon using two interfering focussed UV beams. Early devices exhibit reflection intensities of 80% with

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-
