Solid-state single crystal growth was observed at the perimeter of the crystalline core, and the growth speed along (110) is about 2.7 times faster than that of (001). The grown cladding was single-crystalline as evidenced by electron backscattered diffraction and scanning electron microscopy examinations. From optical transmission measurement at 1550 nm, the far-field distribution of the transmitted light matches well with that of the fundamental mode. With a core size of 30 μm, the refractive index difference between core and clad was measured to be 1.0 x 10-4. From fluorescence mapping on the fiber end face, a very limited amount of the Ti3+ ions in core were diffused into the grown crystalline cladding during the solid-state growth. ? 2020 Optical Society of America under the terms of the OSA Open Access Publishing Agreement. |
