A magnetic dual glasses window structure includes a window blind, provided between two panes of glass, including tilt cords for supporting a plurality of slats and an operating system which includes a shaft attached to the tilt cords and a magnetic actuating device. The magnetic actuating device includes an actuating cord movably and encirclingly attaching to two end portions of the shaft, a pair of resilient elements attached to the actuating cord respectively for applying an urging force against the actuating cord, a magnetic seat connecting between the two resilient elements and positioned adjacent an inner surface of one of the panes of glass, and a magnetic slider positioned adjacent an outer surface of the pane of glass for magnetically driving the magnetic seat to move. Therefore, by sliding the magnetic slider, the actuating cord drives the shaft to rotate for controlling the tilt angle of each of the slats.

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.
