Microwave consolidation of UV photosensitive doped silica for integrated photonics
Microwave consolidation of UV photosensitive doped silica for integrated photonics
Rapid thermal consolidation of doped silica soot in a Silicon Carbide lined kiln subjected to microwave radiation is reported. The silica soot is fabricated through flame hydrolysis deposition and peak temperatures within the kiln reach >1350°C after 18 minutes of irradiation. The glass underwent Newtonian cooling with an e-1 of approximately 5 minutes. Optical characteristics of the planar glass layer are compared against traditional furnace consolidation approaches. Single-mode waveguides and Bragg gratings were direct UV written into the consolidated doped silica, and a propagation loss of 0.34 ± 0.15 dB cm-1 was measured.

Abstract
Rapid thermal consolidation of doped silica soot in a Silicon Carbide lined kiln subjected to microwave radiation is reported. The silica soot is fabricated through flame hydrolysis deposition and peak temperatures within the kiln reach >1350°C after 18 minutes of irradiation. The glass underwent Newtonian cooling with an e-1 of approximately 5 minutes. Optical characteristics of the planar glass layer are compared against traditional furnace consolidation approaches. Single-mode waveguides and Bragg gratings were direct UV written into the consolidated doped silica, and a propagation loss of 0.34 ± 0.15 dB cm-1 was measured.
