Dispositif optique de type guide d'ondes

Optische einrichtung des wellenleitertyps

Waveguide type optical device

Abstract

An arrayed waveguide grating optical multiplexer/demultiplexer according to the present invention including an input channel waveguide, an input slab waveguide, an arrayed waveguide, a polarization dependence eliminating means, an output slab waveguide, a temperature compensating means, and an output channel waveguide is characterized in that the temperature compensating means compensates for the temperature dependence of the optical path lengths in the channel waveguides of the arrayed waveguide, and the polarization dependence eliminating means eliminates the polarization dependence of the optical path length due to the birefringence of the arrayed waveguide and the polarization dependence of the optical path length of the temperature compensating means.
