Explain about the double-crucible method.
Low loss fibers are mostly manufactured by using double crucible and vapour phase deposition method.
The double-crucible method is the mainly common direct melt procedure. The double-crucible process combines the molten rods in a single perform by using two concentric crucibles. Optical fibers are drawn by this molten glass by using a same fiber drawing process as into vapor phase oxidation. A demonstration of a fiber drawing apparatus by using the double crucible process is illustrated in the given figure.

Cosmic censorship conjecture (R. Penrose, 1979) The conjecture, so far completely undemonstrated in the context of general relativity, that all singularities (along the possib
Huygens' construction; Huygens' principle (C. Huygens): The mechanical propagation of any wave (exclusively, of light) is equal to supposing that each point on the wavefront b
why the reflective index of cladding is lower then in core of a fiber optic?
This depends on the arrangement of a beam or column. for a simply supported beam with a point load in the centre of the beam Mmax = WL/4 and will occur at centre span W is the lo
what is meant by physics? and also explain the branches of physics.
Draw the final image formed by two lenses: An optical imaging system consists of two positive lenses (L1 and L2). L1 has a focal length f 1 = 10 cm, and L2 has a focal length
What are intrinsic and extrinsic semiconductors? A semiconductor is a material that has an electrical conductivity among that of a conductor and an insulator. In a semiconducto
