Centre for Promotion of Additive Manufacturing: Optical Computation Chips (CPAM:OCC) is a Additive manufacturing / Photonics Initiative supported by the Ministry of Electronics and Information Technology (MeitY), Government of India, and hosted by the Department of Instrumentation and Applied Physics (IAP), Indian Institute of Science (IISc), Bengaluru.

​

CPAM:OCC brings together the multidisciplinary expertise of IISc Bengaluru and C-MET Pune to establish a national platform for the development of indigenous next-generation photonics manufacturing technologies. The centre focuses on advancing the complete innovation chain—from materials and process development to instrument design, fabrication, and technology translation.

Our mission is to develop scalable manufacturing platforms capable of producing high-precision submicron 2.5D and 3D nanostructures for emerging applications in meta-optics, photonic integrated circuits, optical computation, sensing, imaging, and advanced semiconductor systems.

​

The technologies being developed at CPAM:OCC encompass advanced lithography, nanoimprint manufacturing, additive manufacturing, meta-optics, photonic packaging, and optical system integration. These capabilities are expected to enable transformative solutions across multiple strategic sectors, including:

• Optics and Photonics

• Semiconductors and Electronics

• Automotive Systems

• Aerospace and Space Technologies

• Defence and Security

• Medical Devices and Healthcare

• Quantum Technologies

• Advanced Manufacturing

​

By fostering innovation, indigenous technology development, and industry collaboration, CPAM:OCC aims to accelerate India's journey toward self-reliance in advanced photonics and semiconductor manufacturing while creating globally competitive technologies for future generations
