摘要
为了在波分复用（WDM）设备的阵列波导光栅（AWG）中实现频谱平坦化，我们在输入波导的末端级联了一个特殊的 "A "形多模干涉（MMI）结构。MMI 采用线性展宽函数（LSF）设计，将 1 dB 带宽提高到 0.7 nm，3 dB 带宽提高到 1.6 0.2 nm，插入损耗测量值为 3.5±0.3 dB，信道串扰低于 -30 dB。
A flat-top Arrayed Waveguide Grating base on cascading "A" shape Multimode Interference
To achieve spectrum flattening in the wavelength division multiplexing (WDM) device's arrayed waveguide grating (AWG), we have cascaded a special "A" shape multimode interference (MMI) structure at the end of the input waveguide. The MMI is designed by the linear spreading function (LSF), which increases the 1 dB bandwidth to 0.7 nm and the 3 dB bandwidth to 1.6 0.2 nm, the insertion loss is measured at 3.5±0.3 dB, and the channel crosstalk is below -30 dB.
