title: Integrated 1.3/1.5 μm cyclic AWG router for λ-tunable WDM/TDM-PON.
abstract: We propose a cyclic NxN AWG router that can multi/demultiplex upstream and downstream signals with different channel spacings in different wavelength regions. We fabricated a 4 x 4 AWG router for our novel λ-tunable WDM/TDM-PON using silica-based PLC technology and showed that it can cyclically multi/demultiplex both 20 nm-spaced and 200 GHz-spaced signals at 1.3 and 1.5 μm, respectively.
