| 英文摘要 | PURPOSE:To simply suppress the intensity deviation of the output of a wave collector as well as to contrive miniaturization and integration of the titled light source by a method wherein the deviation of output intensity of beams of light having different wavelengths is effectively cancelled each other out taking advantage of the loss difference existing between ports of the wave collector. CONSTITUTION:Taking advantage of the fact that both of the deviation in the intensity of output light of a plurality of semiconductor laser 22 having different optical wavelengths obtained by changing the distribution constant of a diffraction lattice 24 and the difference of the optical propagation losses existing between the ports of an optical wave collector 23 are independent on the structure of themselves, the semiconductor laser 22 which outputs beams of light having a high light intensity and the input port of the optical wave collector 23 having a larger loss are optically coupled, and in contrast with this, the semiconductor laser 22 which outputs a beam of light of low output light intensity and the input port of the optical collector 23 of smaller loss are optically coupled. Accordingly, a plurality of semiconductor lasers and the input port of the wave collector can be optically coupled respectively, thereby enabling to collectively suppress the output deviation of each optical wavelength in the output of the wave collector. |
