Abstract
An optical device includes an optical waveguide with a block that is fusion spliced to one end. The block has a refractive index approximately equal to the effective refractive index of the waveguide and is of such a length that substantially all the light exiting the waveguide propagates directly to the end of the block remote from the waveguide.
