compact (< 5mm^ 2) 45 cm spiral waveguide composed of CMOS-compatible doped high-
index glass. While both wavelengths have weak dispersion and are near zero dispersion
points, they present different symmetries. At 1550nm, the normal dispersion regime takes
place at longer wavelengths, whereas at 1290nm it is at shorter wavelengths, and we
observe features in the SC spectra that clearly reflect this. In particular, the spectrum at 1550 …
