The project of Microwave Photonics Center, High-speed Optoelectronic Devices, Microwave Photonics and Quantum Information Processing and Microwave Photonics Sensors. According to the information of large-scale microwave photonic projects in the United States, it is known that there are large-scale microwave photonic projects or plans in the United States.

1. The project of "Microwave Photonics Center" funded by the National Science Foundation (NSF) aims to develop new low-light-level devices and optoelectronic devices.

2. The plan of "high-speed photoelectric equipment" initiated by the U.S. Department of Defense aims to develop faster and more efficient military and civilian photoelectric equipment.

3. The project "Microwave Photonics and Quantum Information Processing" of National Institute of Standards and Technology (NIST) aims to study the basic theories and new devices of microwave photonics and quantum information processing.

4. The plan of "Microwave Photonic Sensor" of the National Aeronautics and Space Administration (NASA) of the United States aims to develop a new type of microwave photonic sensor for detecting pollutants, gases and liquids in air and water. The American Microwave Photonics Project (MWP) is a national research project, which aims to promote the development of microwave photonics technology to meet the needs of national security, communication, medical care, energy and other fields. Funded by the US Department of Defense, this project aims to develop a more efficient, flexible and reliable communication and sensor system by combining microwave and photon technologies.
