【Abstract】 The principles of optical waveguide true-time-delay and the applications in phased array antenna are introduced.By the integration of the fluorinated polyimide strip waveguide and the switch matrix,a scheme of true-time-delay module of integrated optical waveguide switch matrix is proposed.Due to the integration of the waveguide and switch on the same substrate,the module has desirable features such as high integration,small size,low cost,good consistency,low insert loss,etc.And according to different optical switch types,the topology of the optical true-time-delay module is analyzed and the combination between switch and waveguide is improved.更多还原
