An apparatus for use in optical communication systems to multiplex/demultiplex an optical signal consisting of an optical channel(s) of distinct wavelength(s) having a select channel spacing within a select wavelength range. The apparatus includes a plurality of optical waveguides aligned generally along the same optical axis with each having a propagating end. At least two of the optical waveguides each propagate a distinct multiplexed optical signal comprising a plurality of channels, with the multiplexed optical waveguides being arranged in a multiplexed linear array. The others of the optical waveguides are single channel waveguides arranged in a two dimensional array with linear rows perpendicular to the multiplex linear array and with each linear row corresponding to a multiplex optical waveguide. A reflective echelle grating is optically coupled to the plurality of optical waveguides along the optical axis and receives an optical signal emitted from at least one of the optical waveguides and detracts the optical signal(s) to at least one other of the optical waveguide(s).
A dense wavelength multiplexer/demultiplexer for use in optical communications systems using optical signals in a select near infrared wavelength range and a select channel spacing, the multiplexer/demultiplexer comprising:
An apparatus for use in optical communications systems to multiplex or demultiplex an optical signal comprising optical channel(s) of distinct wavelength(s) having a select channel spacing within a select wavelength range, the apparatus comprising:
A method of multiplexing or demultiplexing an optical signal in an optical communications system, the optical signal comprising optical channel(s) of a 0.8 nanometer or less channel spacing and different wavelength within a wavelength range between 1520 and 1610 nanometers, the method comprising:
A bulk optic echelle grating for use in multiplexing and demultiplexing optical signals in optical communications systems operating in a near infrared wavelength range, the grating comprising a groove spacing of between about 50-300 grooves/millimeter and a blaze angle of between about 51-53 degrees.
