High resolution optical wavelength power meter reflected optical wavelength scanning device using the same and reflected optical wavelength scanning system using the same

摘要

The present invention relates to a high-resolution optical wavelength power meter, a reflected optical wavelength scanning device and a reflected optical wavelength scanning system using the same. A high-resolution optical wavelength power meter according to an embodiment of the present invention includes a high-resolution arrayed waveguide grating configured to receive an optical signal and distribute it for each channel according to a wavelength band, and a plurality of connected channels corresponding to each of the high-resolution arrayed waveguide gratings. a photo-monitoring unit including a photo-detector array composed of four photo-detectors; a display unit configured to display an output signal according to the wavelength of the optical signal received by the optical monitoring unit; and a control unit that analyzes the received signal of the optical monitoring unit and transmits an output signal according to the wavelength of the optical signal to the display unit.
