DOI: 10.1364/ol.44.002883
Abstract: We designed and experimentally demonstrated an on-chip Fourier transform spectrometer on silicon-on-sapphire. The spectrometer comprises an array of twelve Mach–Zehnder interferometers (MZIs) with linearly increasing optical path delays between MZI arms. The propagation loss of… read more here.

DOI: 10.3390/nano12193394
Abstract: To reduce the built-in positive charge value at the silicon-on-sapphire (SOS) phase border obtained by bonding and a hydrogen transfer, thermal silicon oxide (SiO2) layers with a thickness of 50–310 nm and HfO2 layers with… read more here.
