Abstract
A multi-mode optical fiber includes a glass center for conducting fundamental and high order modes of light waves, the high order modes including a first desired group of high order modes and a second undesired group of high order modes. A cladding surrounds the glass center, the glass center and cladding forming a core. A trench within the cladding surrounding the glass center reflects the first and second groups of high order modes into the core. The multi-mode optical fiber is constructed with a pressure applying element thereover that applies continuous pressure to the core, along the length of the multi-mode optical fiber, such that the at least the first group of desired high order modes are permitted to be transmitted through the core and where the second group of undesired high order modes are suppressed.
