Single wavelength characterization. a Detected output interferogram with TLS-1 input (set at 1584.620 nm) with 6 mW input power when resonance wavelength shift ∆λ = 3.38 nm. b Retrieved spectra with TLS-1 input at 8 mW input power when ∆λ = 3.38 nm. The on-resonance wavelength λon3 = 1584.620 nm and the value of dλ is set to be 0.3 and 0.47 nm, respectively. On-resonance wavelengths are denoted in black and off-resonance wavelengths in red. c Retrieved spectra with TLS-1 input at on-resonance wavelengths when ∆λ = 3.38, 7.38, 11.38, 15.38, 19.38, 23.38, and 27.38 nm, respectively
