A wavelength independent multi-section optical coupler having at least three optical couplers, and at least two differential phase cells. Each optical coupler has two waveguides forming a coupling region having a net coupling value. The coupling value for each coupling region of the at least three optical couplers is different than the coupling values of the other two coupling regions. Each differential phase cell connects adjacent ones of said optical couplers. Each differential phase cell causes a differential phase shift in light signals traversing between the optical couplers, wherein the differential phase shifts of the differential phase cells, and the coupling value for each coupling region are chosen so as to minimize wavelength, and fabrication sensitivity of said wavelength independent multi-section optical coupler for a designed power splitting ratio.

An intermediate structure used to form an integrated optics device comprising a substrate, a cladding on the substrate, at least one real waveguide on the cladding, and at least one dummy waveguide optically coupled with the real waveguide. The real waveguide forms a part of a predetermined planar lightwave circuit. The dummy waveguide does not form a part of the predetermined planar lightwave circuit.

The present invention is directed to an on-chip symmetric optical circuit having one or more integrally fabricated polarization rotators forming a monolithic, solid state polarization independent symmetric circuit. The symmetric optical circuit has at least one integrally fabricated rotator positioned in a plane of symmetry of at least one optical fiber, waveguide or circuit path of the symmetric optical circuit. The folded symmetric optical circuit may be for example a Mach-Zehnder type optical circuit or an arrayed waveguide grating optical circuit.
