GUIDED-WAVE MICROLENS ARRAY APPLICATIONS TO COMPACT 1×8 PLANAR WAVEGUIDE SPLITTERS

摘要

A compact 1×8 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.
