Abstract
A 6.4-THz-spaced 10 × 10 cyclic arrayed waveguide grating (AWG) supporting 64 THz of bandwidth of the T- and O-bands is designed and fabricated. Cyclic operation was realized using only one diffraction order by combining an AWG with double the number of output waveguides and an array of 2 × 1 couplers. The maximum passband peak deviation of the AWG is around 32% of its channel spacing. Such AWG would be useful for coarse T-band applications or for waveband routing in a cascaded AWG configuration.
