C. Dragone et al., WAVE-GUIDE GRATING ROUTER WITH MAXIMALLY FLAT PASSBAND PRODUCED BY SPATIAL-FILTERING, Electronics Letters, 33(15), 1997, pp. 1312-1314
A wavelength router with a maximally flat passband produced by spatial
filtering is described. The router is suitable for long haul and loca
l area optical networks. It is realised in integrated form using silic
a-over-silicon technology. It features a wide passband, low crosstalk
and an excess loss close to 2.5dB.
