Wavelength and polarization insensitive optical splitters fabricated in K/sup +//Na/sup +/ ion-exchanged glass

Abstract

Guided wave one-to-two- and one-to-four-way splitters designed for operation at wavelengths in the region of 850 nm fabricated in K/sup +//Na/sup +/ ion-exchanged glass are discussed. The devices have been characterized, and the split ratio has been found to be wavelength and polarization insensitive over a bandwidth exceeding 200 nm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
