100 °C deposited transparent silicon nitride film for O-band photonic applications
2019
A transparent silicon nitride film deposited at 100 ° is developed by liquid-source chemical vapor deposition (LSCVD) method. With a combination of the series of spectrometric analysis, we reveal that the waveguide shows low propagation loss $( \sim 1.0$ dB/cm) with practically applicable high refractive index $( \sim 1.85)$ in the O-band (1260-1360 nm).
