Abstract

Waveguide Bragg gratings were fabricated by plasma-enhanced chemical-vapor deposition followed by irradiation with KrF excimer laser light through a phase mask. The period of the Bragg grating was 0.53 μm, and the Bragg wavelength was ~1.53 μm . The temperature dependence of the Bragg wavelength was 11 pm/°C for a 10GeO2 –90SiO2(mol.%) core waveguide on a Si substrate, and the Bragg wavelength shift was successfully reduced to 5.0pm/°C by use of a 14GeO2–12B2O3–74SiO2 (mol.%) core and a crystallized glass substrate with a thermal-expansion coefficient of -2.0×10-6(/°C) .
