Optical relative humidity sensor based on a hollow core-photonic bandgap fiber
We propose a novel relative humidity (RH) sensor based on a hollow core-photonic bandgap fiber (HC-PBF) using a wavelength scan and a reference technique in this paper. The wavelength scan of water vapor absorption peak around 1368.59nm is realized by injecting sawtooth modulated current to a DFB la...
