AGGREGATION WAVELENGTH DIVISION MULTIPLEXING NODE MODULE

摘要

The present invention relates to a configuration of and a method for manufacturing a wavelength division multiplexing node module having aggregated, as optical components used in a wavelength division multiplexing (WDM) node, a wavelength multiplexer (MUX), a wavelength demultiplexer (DMX), and a channel monitor. The aggregation wavelength division multiplexing node module is configured to: use two arrayed waveguide grating devices manufactured on one aggregation optical device chip, one as a wavelength MUX and the other as a wavelength DMX; couple, to an output portion of the arrayed waveguide grating device used as a wavelength DMX, a chip manufactured with an aggregation optical light tap coupler for diverging a part of an outputting light in array; and composing a photodetector array on the output to comprehend the signal status of each of communication channels. In addition, the arrayed waveguide grating devices used as a wavelength MUX and a wavelength DMX comprise a temperature-nondependent arrayed waveguide grating device so as to enable a stable operation unrelated to the change in the surrounding temperature.
