碩士 === 中華技術學院 === 機電光工程研究所碩士班 === 93 === The direction coupler is composed by the access waveguide and the coupling section, when the light by inputs the access waveguide to enter the coupling section, generally thought the waveguide the essence wants unusual good, but speaking of the system regulation is unable to achieve 100% essence, when, the present paper simulated the light by to input the waveguide entered the coupling region part, because inputs the loss which the waveguide the displacement created. The result discovery input waveguide suitable displacement can the effective promotion coupling efficiency. Take this as the foundation, we proposed substitutes for the input waveguide by the PSW’s, our visible this overhead construction is a continuously displacement the bending waveguide. This novel access waveguide overhead construction not only can the effective promotion coupling efficiency, simultaneously reduce the length to reach 7,600 μm, also no matter is regarding InGaAs/InP or the SiO2 two kind of different materials all have the similar effect. Finally we use three groups of directions couplers, unifies the new input waveguide overhead construction string which we proposed to connect a group of 2X6 light switch, the light switch are partial we to choose the SiO2 material to do for simulates the base material.
