Photonics has made vast improvements to our daily lives over the past decade revolutionizing modern communication systems, displays, lighting, manufacturing, defense and medicine. To increase the impact of photonics even further, a reduction in the size, weight and power along with cost of the devices is required. This opens a route towards the development of photonic integrated circuits leveraging the multi-billion-dollar silicon electronic manufacturing infrastructure. There has been a recent focus on using silicon for photonics; however silicon is a modest optical material with high losses, and does not support laser action, thus preventing all-optical integration. This has motivated research into integrated photonics using alternative platforms. I will discuss two areas of my research on integrated photonics in this talk. Firstly, I will present the development of on-chip pulsed lasers with world-record performance for applications in frequency metrology, telecoms and astronomy. I will then focus on integrated nonlinear optical signal processing using the interaction of light (photons) and sound (phonons) in a material and will focus on one of the applications: RF filtering. I will finally discuss the potential for possible electronic-photonic-phononic hybrid integration and will present my perspective on how this field will evolve in the future.
Amol graduated from the Delhi College of Engineering, India, with a B. Eng in Electronics and Communications in 2008. He received an Erasmus Mundus Scholarship to pursue an MSc in Photonics from the Gent University, Belgium; VUB, Belgium and the University of St. Andrews, UK. During his time at St. Andrews, he worked on the analogues of black holes in optical fibers. In 2010 he received an EPSRC scholarship to carry out his doctoral research at the Optoelectronics Research Centre (ORC), University of Southampton, UK. During the course of his PhD, he developed ultrafast waveguide laser sources with world-record performance for applications in non- linear microscopy and optical frequency metrology. After graduating in December 2013, he received an EPSRC doctoral prize fellowship to work on power-scaling of mode-locked waveguide lasers and using graphene in pulsed laser systems at the ORC. He joined CUDOS at the University of Sydney in May 2015 to work on integrated nonlinear signal processing. He has more than 60 publications including 18 Journal papers and 3 post-deadline presentations.
