Join the OSA Integrated Optics Technical Group for this webinar featuring a presentation from Dr. Anuradha Agarwal from the Massachusetts Institute of Technology Electronic Materials Research Group. During this hour-long webinar, Dr. Agarwal will present data on using silicon microphotonics in liquid sensing, methane sensing, PbTe waveguide-integrated detection, RCE MIR multispectral detection, and LWIR detection using PbSnTe.

The webinar also will highlight three case studies that were performed in conjunction with MIT’s Sloan School of Management in order to predict the future of integrated photonics sensing. One example case study that will be discussed is oil and gas sensing along pipelines, where it is envisioned the integrated photonics sensor network will minimize the frequency of human checks or even make them redundant.

What You Will Learn:

  • A vision for the future of silicon integrated photonics in the field of sensing, using early experimental data as well as business case studies.
Who Should Attend:
  • All interested in learning about sensors, specifically silicon-based integrated photonic sensors.


Dr. Anuradha Agarwal, Massachusetts Institute of Technology

Dr. Anuradha Agarwal received her doctoral degree in Electrical Engineering from Boston University in 1994, where she investigated the spatial extent of point defect interactions in silicon. She has been at MIT's microphotonics center since 1994, except for a short stint (2001-2004) at Clarendon Photonics, where she was part of a team of engineers developing a novel optical filter. Currently as Principal Research Scientist, she is developing integrated CMOS compatible linear and non-linear materials for photonic devices, especially in the mid-IR regime, for hyperspectral imaging and chem-bio sensing, because most chemical and biological toxins have their fingerprint in this range. She has over 100 journal and refereed conference publications, 6 awarded patents and 5 pending patents. Her work on MIR materials and devices is creating a planar, integrated, Si-CMOS compatible microphotonics platform which will enable on-chip imaging and sensing applications.
