摘要	The present invention provides an optical multiplexer/demultiplexer which can demultiplex a multiplexed optical signal having a number of wavelength bands into respective wavelength regions, or multiplex light having respective wavelength regions in the field of optical communications. That is, light gained by multiplexing light having wavelengths .lambda.1, .lambda.2, .lambda.3 and .lambda.4 is emitted from an optical fiber (9a) and the optical axis thereof is bent by a micro lens (12a) of a micro lens array (14) so that the light is converted to parallel light which is then reflected from a mirror layer (19) so as to enter into a filter layer (17). A filter (17a) transmits only light having wavelength .lambda.1, and light having other wavelengths is reflected and again reflected by the mirror layer (19) so as to enter into the filter layer (17). The optical axis of light that has transmitted through the filter (17a) is bent by a micro lens (12c) so that the light is coupled to an optical fiber (9c). Light having wavelength .lambda.1, .lambda.2, .lambda.3 and .lambda.4 is taken out from the light emitting ends of optical fibers (9c, 9d, 9e and 9f), respectively. 168
其他摘要	本发明提供了一种光学多路复用器/多路分离器，它可以将具有多个波段的多路复用光信号多路分解成各个波长区域，或者在光通信领域中多路复用具有各个波长区域的光。也就是说，通过多路复用具有波长λ1，λ2，λ3和λ4的光而获得的光从光纤（9a）发射并且其光轴被微透镜弯曲（ 12a）微透镜阵列（14），使得光被转换成平行光，然后从镜层（19）反射，以便进入滤光层（17）。滤光器（17a）仅透射具有波长λ1的光，并且具有其他波长的光被镜面层（19）反射并再次反射，以进入滤光层（17）。透过滤光器（17a）的光的光轴被微透镜（12c）弯曲，使得光耦合到光纤（9c）。从光纤（9c，9d，9e和9f）的发光端分别取出波长为λ1，λ2，λ3和λ4的光。 168
主权项	An optical multiplexer/demultiplexer, wherein plurality of wavelength selecting elements of which the transmission wavelength bands are different from each other and a light reflecting surface are made to face each other, and thereby, an optical guiding means for guiding light by making light being reflected between the light reflecting surface and the respective wavelength selecting elements and for multiplexing or demultiplexing light having different wavelengths is formed, a transmission means for transmitting light having plurality of wavelengths is coupled to light having plurality of wavelengths or wavelength bands that is guided within the optical guiding means, plurality of light inputting/outputting means are placed on the same side as the transmission means relative to the optical guiding means in a manner where the direction of the optical axis becomes approximately perpendicular to the direction in which the wavelength selecting elements are aligned, and a deflection element for converting the direction of the optical axis of light that has transmitted through each of the wavelength selecting elements into one that is parallel to the direction of the optical axis of the respective light inputting/outputting means, or for converting light that is parallel to the direction of the optical axis of each of the light inputting/outputting means into the direction of the optical axis of light that transmits through each of the wavelength selecting elements is provided between each of the light inputting/outputting means and each of the wavelength selecting elements.
