Abstract

We report fabrication of 1×2 and 1×4 optical waveguide splitters in BK-7 glass using 270 fs, 1030 nm laser. Transverse writing technique is used to inscribe optical waveguide splitters 250 μm below the glass surface. We adopted a novel non-stop complete splitter writing approach involving variable writing speed during multi scan. The fabricated 1×2 and 1×4 splitters show 0.1 dB and 0.3 dB uniformity respectively at 1550 nm.
