The present disclosure relates to a PON power meter using multi input type AWG, including a first input part into which a first signal is input, wherein the first signal has S optical signals whose wavelengths are different from each other; a second input part into which a second signal is input, wherein the second signal has P optical signals whose wavelengths are different from each other; an AWG that distributes the input signal to M output waveguides according to wavelength band; a detection part configuring (S+P) detection channels by connecting a photodetection element to only (S+P) output waveguides of the M output waveguides of the AWG; and an output part that outputs a strength of the signal detected by the detection part.

PON powermeter using multi input type AWG

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.
