Ultra-Wide-Band Adiabatic Coupler As a Building Block for 2�?32 PLC Splitter
(Citations: 1)
We demonstrate adiabatic wavelength insensitive 2times2 PLC coupler with less than 0.6 dB variation over 1260- 1630 nm range and better than 0.25 dB PDL. We use it to build process tolerant 2times32 splitter having excellent optical performance.
