We report on our observation of thermal control transmission spectra a micro-ring resonator coupled to low finesse etalon. Thermal tuning the device changes coupling strength and losses between etalon ring resulting in wide variety line shapes ranging from symmetric asymmetric Fano-like electromagnetically induced transparency (EIT)-like behavior. The capability modify spectral by thermally two resonators has obvious applications optical communication networks relevance sensor where it may be exploited for developing novel cutoff switches significant, deleterious effect measurement uncertainties large dynamic range sensors.
