A preparing method of rude wavebranch multiplexer and its optical fiber coupler for use of a base structure built by N numbers of optical fibre couplers as each optical fibre coupler divides light signal into two path as per wavelengths; the two path of signals are separately sent to the optical fibre coupler at the next stage to form N+1 channels as each channel of output light signal is connected with a filter in series to increase channel bandwidth and isolation ability. A preparing method of coupler is as follows: a) selecting optical fibre of inner packaging layer in reflecting rate to be increased step by step type as coupling material; b) using strong coupling mode and drawing cone by fusion to make selected material waveguide with fibre core near closely as well as to make centre wavelength interval period of optical fibre coupler at the next stage two times of optical fibre coupler at the last stage. |
