Abstract :
Summary form only given. We report, for the first lime, waveguide gratings fabricated in intrinsically low-loss (0.2 dB/cm with no annealing) germanosilica waveguide layers without the use of any material presensitization. The waveguides were grown by a novel technique called hollow-cathode PECVD, which, unlike conventional PECVD, can produce low-loss waveguides without the need to postanneal films.
