Abstract :
The performance of a novel 1*8 optical power splitter is demonstrated. Consisting of seven three-guide power couplers connected in a cascade manner, the splitter has a relatively short length of 11 mm. The use of a tapered waveguide in the constituent couplers should make it possible for this power splitter to provide a wide bandwidth and little polarization dependence. Also it has the advantage of strong tolerance to the waveguide parameter deviation.<>
