Abstract
PURPOSE: To obtain a transmission type optical fiber having the same excellent characteristics as an optical filter possessing a great number of layers, by using an optical filter inferior in characteristics with a smaller number of layers.
CONSTITUTION: An optical filter 1 is held by transparent plates 2, 2, and a plurality of total reflection mirrors 3, 3... are disposed on the surface of the transparent plates 2, 2. When lights having different wavelengths λ1, λ2 enter in the direction of the arrow in the drawing, these lights are reflected by the total reflection mirror 3 and are transmitted through the optical filter l five times in the drawing. On the other hand, the lights reflected by the optical fiter 1 escape into the space as shwon by the broken lines in the drawing. Therefore, when leaving to the upper right side, the light of wavelength λ2 is largely attenuated, but the attenuation of the light of wavelength λ1 is small. That is, the light of wavelength λ2 has a large transmission loss, and the light of wavelength λ1 has a small transmission loss, so that pure exit lights may be obtained.
