Mach Zehnder interferometer - array guided wave road lattice and plane surface light wave circuit tip/chip

摘要

As for this invention, without deteriorating MZI AWG quality, you take and the Mach Zehnder interferometer which can guarantee number - you offer the array guided wave road lattice and the plane surface light wave circuit tip/chip. The Mach Zehnder interferometer which relates to one execution form of this invention - the array guided wave road lattice (MZI AWG) 10 the Mach Zehnder interferometer (MZI) the array guided wave road lattice which uses 20 and MZI20 for the input guided wave road (AWG) has with 30. FSR of MZI20 was matched the channel interval of AWG30. The input side coupler 21 of MZI20 and output side coupler 22, center is arranged on extended line A_{0 in the} straight line which ties with the center b of the other end face 31b which is the end face of the circular arc condition which from of a the end face 31of a one side of input throb guided wave road 31₀ and this center a₀ designates focal length Lf as radius₀
