    Abstract: An optical fiber (1) includes (i) an inner core (111) whose refractive index distribution has an a profile, (ii) an outer core (112) which surrounds the inner core (111), and (iii) a clad (12) which surrounds the outer core (112). In the optical fiber (1), Rd is set to not less than 0.15, where Rd is a ratio of a refractive index difference between the outer core (112) and the clad (12) to a refractive index difference between a center part of the inner core (111) and the clad (12).

    Abstract: There is provided a monocrystalline gallium nitride localized substrate suitable for manufacturing electronic-optical united devices in which electronic devices and optical devices are mixedly mounted on the same silicon substrate. An area in which monocrystalline gallium nitride 410 is grown is locally present on a silicon substrate 100 by forming silicon carbide 200 on the silicon substrate 100 to locally form the monocrystalline gallium nitride 410 on the above-mentioned silicon carbide 200. Silicon nitride 220 is used as a mask in forming the above-mentioned monocrystalline gallium nitride 410.
