Abstract

See full text

A dense wavelength multiplexer/demultiplexer for use in optical communication systems using optical signals in a select near infrared wavelength range and a select channel spacing includes at least two multiplex optical waveguides each propagating a distinct multiplexed optical signal comprising a plurality of channels. The multiplex optical waveguides are arranged in a linear array. A two dimensional array of single channel waveguides is arranged in linear rows perpendicular to the multiplexed linear array with each linear row corresponding to a multiplex optical waveguide and the number of single channel waveguides in each row being at least equal to the number of channels in the multiplexed optical signals. The single channel waveguides each have a center and the centers of adjacent single waveguides in each row are spaced a select distance. A collimating/focusing optic is optically coupled between the multiplex and single channel waveguide arrays and has an optical axis and a select focal length.
