Abstract
A multi-wavelength optical signal receiving apparatus receives a multi-wavelength optical signal, demultiplexes the received optical signal to convert into an electric signal. The multi-wavelength optical signal receiving apparatus includes a demultiplexing part including a demultiplexer configured to divide the received multi-wavelength optical signal into a plurality of optical signals by wavelength, a photoelectric conversion part to convert the optical signals into electric signals and amplify the electric signals, and at least one lower securing plate configured to couple the parts by an active alignment method. Accordingly, an additional polishing or coating process is not required, which simplifies the manufacturing process, and it is possible to manufacture the apparatus in blocks, thereby increasing mass-productivity.
