| Popis: | A $1\times 8$ optical splitter with integrated fiber-positioning grooves was fabricated by simultaneous formation of the waveguide cores and grooves. The waveguide cores were realized by intaglio etching of a fused-silica wafer and subsequent core filling, followed by the deposition of an overcladding layer. Fiber-positioning grooves were then formed by wet etching the silica wafer with the use of a highly selective SiN x mask. Passive alignment was accomplished by guiding the fibers into the grooves, which is favorable for automated mass production of splitter modules. The resulting $1\,\times \,8$ splitter module exhibited a small insertion loss of 59 dB. It yielded good reliability during a damp heat test at 85 °C and 85% humidity, and the insertion loss varied by |
