Abstract
Provided are an optical receiver having a wavelength recognition function, and a device and method for recognizing wavelengths using the same. The optical receiver according to an embodiment of the invention includes a splitter configured to split light intensity of input optical signals, a first receiver configured to photoelectrically convert the optical signals split using the splitter, a filter having different pass band characteristics based on wavelengths of the optical signals split using the splitter, a second receiver configured to photoelectrically convert the optical signals passing through the filter, and a comparator configured to compare the optical signals respectively, photoelectrically converted by the first and second receivers and recognize wavelengths of the input optical signals.
