Abstract: Integrated photonics, particularly silicon-based photonic circuits, has revolutionised optical signal processing applications in
communication, sensing, and computing. Building on scalable and flexible fabrication technology, monolithic and heterogeneous
integration has mitigated the limitations in the silicon photonics platform. In this talk, I will share our exploration of exploiting passive
silicon technology developed at IISc for communication, RF signal processing and sensing. Integration of electro-optic and
phase-change materials is key to extending the functionality and application space of traditional silicon photonics platforms. We shall
discuss schemes that will help to realise energy-efficient neuromorphic photonic circuits. While telecom wavelengths dominate PIC
developments, lower wavelengths play a key role in extending the application space to spectroscopy and biosensing. I will present some
compelling reasons for developing circuits operating in lower wavelengths and some demonstrations of circuits with integrated WDM
and on-chip detectors. Furthermore, photonic circuits could be used to enable and enhance signal transduction. By integrating
photonic with micro-mechanics, we were able to demonstrate state-of-the-art displacement detection down to the picometer scale.
While there are a plethora of disruptive technologies that photonic circuits could enable, having scalable and reliable fabrication
technology is essential. In this talk, all the demonstrations will be based on the indigenous process and material developed at the Indian
Institute of Science, Bangalore.
