Abstract

We have developed an $N \times N$ cyclic-frequency router with improved performance by employing two types of modified configuration; a uniform-loss and cyclic-frequency (ULCF) arrayed-waveguide grating (AWG) and an interconnected multiple AWG. We have demonstrated a compact 50-GHz-spacing 64$\,\times\,$64 ULCF-AWG router with low and uniform insertion losses of 5.4–6.8 dB and frequency deviations from the grid of less than $\pm {8}~{\rm GHz}$. We have also demonstrated a 100-GHz-spacing 8$\,\times\,$8 interconnected multiple-AWG router with a practical configuration, very low and uniform insertion losses of 2.3–3.4 dB, and frequency deviations from the grid of less than $\pm {6}~{\rm GHz}$. We discuss the suitable or realizable scale $N$ of the two types of routers by comparison with a conventional AWG router in terms of optical and dimensional performance and productivity.
