(a) The Si-rich SiNx micro-ring based transmission spectrum. (b) The notched transmittances of the Si-rich SiNx micro-ring waveguide at different temperatures. (c) The peak transmitted power of the Si-rich SiNx based channel waveguide vs. the incident peak power at a wavelength of 1550 nm. (d) The simulated wavelength shift on the probe transmission spectra before and after pumping the micro-ring waveguide resonator.
