Optical demultiplexer/multiplexer for polymer fiber transmission to transmit data in e.g. home area, has total reflection forming unit with boundary surface that is inclined towards optical axis so that beam wavelength portion is reflected

摘要

The demultiplexer/multiplexer (2) has total reflection forming unit (5) integrated in an optical path of a light in a polymer base body (1). The body includes medium i.e. air, with a refractive index, which is smaller than a refractive index of the body. The forming unit includes a boundary surface, which is inclined towards an optical axis of falling light beam such that a wavelength portion of the beam is reflected into an uncoupling element connecting unit (13) by total reflection during transmission of the light from the body into the forming unit. Independent claims are also included for the following: (1) a method for demultiplexing light signals of different wavelengths (2) a method for multiplexing light signals of different wavelengths (3) a method for manufacturing an optical demultiplexer/multiplexer for polymer fiber transmission.
