This Small Business Innovation Research Phase 1 research project aims to investigate the feasibility of a super-linear optical modulator technology. This innovation involves a unique and complementary combination of Phase Modulator (PM) and weak Gires-Tournois Resonator (GTR) modulator inside a reflective-type modulator. This modulator has other superior features such as broadband operation, high tolerance characteristics, simple design structure, small footprint, and low-cost potential. This research will focus on the design, simulation, fabrication, and measurement on this ultra-linear waveguide-type optical modulator designed to operate below GHz ranges. The impact of this project has broad commercial, military and scientific significance and represents a major, on-going engineering challenge because of its fundamental role in the overall performance of analog fiber-optics transmission links. In the commercial arena, linearized modulators are key devices in ultra-dense cable television (CATV), Radio-over-Fiber (RoF) communications, broadband wireless access, cellular/personal communication and other mobile platform antenna systems. In the military arena, linearized modulators with wide bandwidth and high tolerance features are in demand for radar jamming, antenna-remoting, signal distribution for phased array antenna applications.

该小型企业创新研究第一阶段研究项目旨在研究超线性光调制器技术的可行性。 这项创新涉及反射型调制器内的相位调制器 (PM) 和弱 Gires-Tournois 谐振器 (GTR) 调制器的独特且互补的组合。该调制器还具有其他优越特性，例如宽带操作、高容差特性、设计结构简单、占地面积小和低成本潜力。这项研究将重点关注这种设计用于低于 GHz 范围的超线性波导型光调制器的设计、模拟、制造和测量。该项目的影响具有广泛的商业、军事和科学意义，并且由于其在模拟光纤传输链路的整体性能中发挥着根本作用，因此代表了一项重大的、持续的工程挑战。在商业领域，线性调制器是超密集有线电视 (CATV)、光纤无线电 (RoF) 通信、宽带无线接入、蜂窝/个人通信和其他移动平台天线系统中的关键器件。在军事领域，雷达干扰、天线遥控、相控阵天线应用的信号分配需要具有宽带宽和高容差特性的线性化调制器。
