Guided‐wave microlens array applications to compact 1 × 8 planar waveguide splitters

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 applica- ble for compact and wide-bandwidth integrated optical devices. © 2004 Wiley Periodicals, Inc.
