Guided-wave microlens array applications to compact 1x8 planar waveguide splitters

Abstract

A compact 1 x 8 waveguide splitter using a guided-wave microlens array is presented and analyzed to show low insertion loss and output imbalance of 0.28 and 0.15 dB, respectively. The analysis results show that the proposed equal-power splitter with insensitive wavelength responses and acceptable fabrication tolerances is applicable for compact and wide-bandwidth integrated optical devices.
