Light wavelength division multiplexing structure of the prior art is general as shown in Figure 1: by an optical fiber input multi-wavelength signals in double optical fiber head 101, collimates through the first GRIN Lens 102, is then incident in dielectric coating filter 103；Incide the second lens 104 through the transmission peak wavelength optical signal of dielectric coating filter 103 selective transmission, assemble through the second lens 104, be coupled into single fiber head 105；Assembling through the first GRIN Lens 102 from all the other wavelength channels of dielectric coating filter 103 surface reflection, being coupled in another root optical fiber in double optical fiber head 101, thus completing wavelength-division multiplex function。
Wherein, the 6th glue 114 is used for the mounting medium Thin Film Filter 103 planar ends in the first GRIN Lens 102, and the 5th glue 113 is for fixing the beveled end of the first GRIN Lens 102 and double optical fiber head 101；First glue 109 is for being fixed on double optical fiber head in first sleeve 106, then is fixed in the second sleeve pipe 107 by the second glue 110；3rd glue 111 fixes the second GRIN Lens 104 and single fiber head 105 in the 3rd sleeve pipe 108, and the 4th 112, glue the 3rd sleeve pipe 108 is fixed in the second sleeve pipe 107。
The wavelength division multiplexer of prior art has problems in that operating distance and the single optical fiber calibrator of size with a tight waist are fixed in use in advance, when double-fiber collimator and single optical fiber calibrator couple, except operating distance and size with a tight waist, also has more serious coupling mismatch, especially for dense wave division multiplexer part。
The light wavelength division multiplexing of prior art uses and fixes operating distance and the collimator of size with a tight waist in advance, under such restrictive condition, single optical fiber calibrator and double-fiber collimator carry out timing, by the pitching of micropositioning stage, lifting, rotation, translation etc., angle mismatching when can only eliminate single optical fiber calibrator and double-fiber collimator coupling and horizontal mismatch loss, it is impossible to solve mismatch loss with a tight waist and axial mismatch loss。Simultaneously because intrinsic angular compliance, causing the uneven of the second glue 110 and the 4th glue 112, there is intrinsic temperature characterisitic defect in device。
