A fiberized highly birefringent glass micrometer-size ridge waveguide
We report the fabrication of a fiberized micrometer-size ridge waveguide. No extra loss from the fabrication process was observed in the fiberized ridge waveguide. A high birefringence of 9.510?3 was measured in the waveguide at 1.55?m. We propose to use the fiberized ridge waveguide as a highly sensitive optical sensing device. Fusion splicing was successfully employed to splice the waveguide to a conventional silica fiber.
