Abstract:
An optical signal detector is provided that detects an optical signal from an optical source using a plurality of optical sensors having different wavelength selectivities, thereby determining the peak wavelength of the optical signal and measuring the power of an optical signal corresponding to the peak wavelength. According to the optical signal detector, separate optical filters are not required and space and costs attributable to the installation of the optical filters can be saved, and thus there are effects in that the overall size and manufacturing costs of the device can be reduced.
