基于SOI非对称马赫曾德尔结构的集成矢量和微波光子移相器
Integrated vector sum microwave photonic phase shifter based on asymmetric Mach-Zendner structure in SOI
摘要
Abstract
An integrated vector sum microwave photonic phase shifter（MWPPS） based on the asymmetric Mach-Zendner structure in Silicon on Insulator（SOI） rib waveguides was designed and fabricated for the first time.A fixed true time delay of 47 ps was achieved by a length difference of 3 983 μm between the two asymmetric arms.Then two thermo-optical Variable Optical Attenuators（VOAs） were integrated in the two arms respectively to tune the optical power individually.The phase shift ranging from 0° to near 180° for a 10 GHz microwave signal has been achieved by the RI variation of 06×10-3 in VOAs.The device which has a very compact size could be easily integrated in silicon optoelectronic chips and expected to be widely used in Optically Controlled Phased Array Radars（OCPARs）.关键词
