Abstract
A reflected light wavelength scanning device having a silicon photonics interrogator is provided. The device includes: a light source module for outputting broadband light; an optical sensor that receives light output from the light source module through a circulator, reflects light in a specific band to the circulator, and transmits light in a band other than the specific band; and an interrogator for selectively injecting the polarized light by separating the polarized light from the reflected light input through the circulator.
