摘要:
An inflatable platform that is utilized on the ocean or other bodies of water for relaxation, entertainment, or other recreational purposes includes two floating bodies. The larger floating body has a recess with a mesh panel so the user may access water filtered by the mesh panel while relaxing on the larger floating body. The user may place the smaller floating body next to the larger floating body to create more space for another user or may put the smaller floating body into the recess and use the present invention as a swim platform, tanning deck, or other recreational purpose.

A large mode field diameter optical fiber is disclosed. It is a single mode optical fiber which has a core and a cladding. The core of this fiber has two regions, an inner core region and an outer core region which has a refractive index lower than that of the inner core region. The inner core region is doped with a rare-earth element, such as Er2O3, and a co-dopant, such as Al2O3, and the outer core region is doped with a dopant such as GeO2. The types and amounts of the dopants and co-dopants are adjusted to obtain a fiber with a mode field diameter greater than 5.5 μm at a wavelength of 1550 nm.
