设计了基于宽度抛物线型和孔径渐变的一维(1-D)光子晶体(PhC)纳米梁腔.通过FDTD的计算模拟,设计的这种纳米梁腔可以实现超高Q值1.8×10~7,同时拥有超小模体积V～0.04(λ/n)~3,在继承抛物线型和渐变孔径型纳米梁腔高Q的基础上,进一步降低了模体积V.我们设计的这种腔具有紧凑,低制造工艺要求以及高Q/V值等优点,在未来应有广泛应用.
A one-dimensional (1-D) photonic crystal (PhC) nanowire beam cavity based on width parabola and aperture grading was designed.Through the computational simulation of FDTD, this kind of nanowire beam cavity designed can achieve high Q value of 1.8 × 10 ~ 7 , And at the same time has the ultra-small mode volume V ~ 0.04 (λ / n) ~ 3, which further reduces the module volume V based on the inheritance of the cavity height Q of the parabolic and tapered aperture type nanobeam V. The cavity we designed has a compact , Low manufacturing process requirements and high Q / V value, etc., should be widely used in the future.
