Project
Expected deliverables of the research
- Design and demonstration of SOI based 2x2 MZI tunable basic unit (TBU) - the fundamental building block for programmable photonic integrated circuits.
- Process development of low-loss SiN waveguide technology by leveraging existing facilities at the Centre for Nems and NanoPhotonics (CNNP), IIT Madras.
- Photonic processor chip design and tape-out through multi-project wafer (MPW) runs
- Electronic controller/driver chip design and tape-out.
- Developing semi-automated characterization facility for fabricated photonics/electronics chips.
- Fiber pigtailing and packaging of the fabricated chips in collaboration with Si2 microsystems and their testing.
Current status
- Design and fabrication of SOI based MZI TBU in progress
- Process development of SiN waveguide technology in progress
- 1st chip design consisting of passive building blocks for a photonic integrated circuit has been sent to the foundry (AMF, Singapore) for tape-out.
- The necessary upgradation of the existing e-beam lithography system has been completed - much needed for defining critical photonic integrated circuit components.
- Procurement of equipment for characterization facilities in progress.
- Photonics Chip Packaging rules are being developed with the collaboration of Si2 Microsystems, Bengaluru.

Societal impact
The centre of excellence is proposed based on research outcomes and contributions in the area of silicon photonics during the last 14 years at IIT Madras, there is no hazardous societal impact except the promise of forward looking Make in India and Atmanirbhar Bharat in the domain of academic research and technology development. The immediate need of developing photonic integrated circuit technology is to accelerate wide-spread applications in the area of 5G/6G, Multi-band RADAR, QKD for secured communications systems, etc.
Sustenance statement
- International collaborations bring in research collaboration as well as student/faculty exchange programs.
- Induction of new faculty members to the core research team for multidimensional research outcomes and raising project funds from industry as well as from government agencies.
- Besides creating IITM startups, collaboration with reputed industry partners have been planned for technology transfer and prospective commercialization of the prototype/product.
