Claims
- 1. A structure for coupling optical fibers, comprising:
- a first portion including a first optical fiber and a second optical fiber, said second optical fiber having a diameter substantially equal to a diameter of the firs optical fiber;
- a second portion including the first optical fiber and a second optical fiber;
- a first conic region formed by a fusion of the first optical fiber and the second optical fiber and having a first end adjacent said first portion, whereby the first end of the first conic region has a larger cross-section than a second end of the first conic region;
- a fiber cavity having a first end adjacent the second end of the first conic region, said fiber cavity having a diameter smaller than the diameters of the first optical fiber and the second optical fiber; and
- a second conic region formed by a fusion of the first optical fiber and the second optical fiber and having a first end adjacent a second end of the fiber cavity, whereby the first end of the second conic region has a smaller cross-section than a cross-section of a second end of the second conic region, said second end of the second conic region being adjacent said second portion.
