Centre for Programmable Photonic Integrated Circuits and Systems (CPPICS) is one of the centre of excellence (CoE) initiatives by the Ministry of Electronics and Information Technology (MeitY), Govt. of India. It is hosted by Department of Electrical Engineering, IIT Madras with a long-term mission for catering R&D in the area of programmable photonic integrated circuits and systems using CMOS compatible silicon photonics technology for solving various levels of complex problems. The immediate focus of this CoE is to provide better solutions for microwave and quantum photonics applications such as advanced photonic processors to be used in high-performance RF transceivers, scalable linear optical quantum computing (LOQC) processors for the next generation qubit computation, and chip-level quantum key generation and distribution circuits, etc.

PCM is an emerging memory technology exploits unique feature of chalcogenide-based phase change materials that undergo ultrafast and reversible phase transitions between a highly resistive amorphous state (digital “0”) and a conducting crystalline state (digital “1”) using nanosecond (ns) electrical pulses. Such permanent, yet reversible phase transitions (more than 10 million cycles) are stable over 10 years, ensures non-volatility as well as faster programming (ns) and therefore, PCM is being demonstrated as a strong candidate not only for next generation high speed non-volatile memory but also  ‘universal memory’ for future high speed computing devices.

Post silicon, Gallium Nitride (GaN) has emerged as the WONDER material that has the potential to disruptively change the future of semiconductor devices. Bolstered by its unique material and device properties, it is finding extensive applications both in power and RF domains; e.g. 5G, Power switches,etc. This technology is expanding to capture the market of electric vehicles, besides being pushed towards application in extreme environments (automobiles, low earth orbit satellites, high temperature and radiation hard application) and even for quantum computing.

At CNNP, GRAND group works towards development of indigenous GaN technologies and systems through detailed physical analysis, to meet the nations need for a sustainable and prosperous future.
