Abstract
A narrowband twisted optical fiber wavelength division multiplexer ('WDM') and a method for fabricating the WDM. The WDM includes a twisted pair of first and second optical fibers that are fused together, each of the first and second fibers having a first and second end. In the WDM, when a first and second light are applied to the first end of the first fiber, they will appear on the second end of the first fiber and the second end of the second fiber, respectively. When the first light enters the second end of the first fiber, and the second light is applied to the second end of the second fiber, they will both appear on the first end of the first fiber.
