Micro and Nano Devices Laboratory

The laboratory has been planned by keeping both the teaching and research requirements of SENSE. With the existing of Curriculum for Applied Learning (CAL) theme, the Micro and Nano Devices Laboratory caters to courses in the UG as well as PG curriculum including Final Year Project. UG and PG students are doing their RBL and Final year projects in different domains of expertise of the faculty of the Micro and Nano Devices Group.
The laboratory has been planned for MEMS design (using commercially available CAD tools such as Intellisuite), Nanoelectronic Device Simulations using TCAD Sentaurus tools and Synthesis and Characterization of Novel Nanomaterials towards Micro and Nano Devices fabrication activities.

About the Optics Research Lab:

The Optics Research Laboratory was established in 2013 with a vision to explore the areas of optical imaging, sensing, signal and information processing and to develop technologies, based on their applications. In this lab, there are ongoing research projects funded by government research agencies. Our program provides an exciting training opportunity for students in undergraduate, postgraduate and doctoral studies and postdocs who wish to explore the areas of optical imaging, optical sensing, optical experiments and signal processing

We aim to address the questions in the following key research areas from the perspectives of theoretical, computational and real-time experiments:

  • Optical imaging
  • Computational optical imaging
  • Compressive sensing
  • Digital holography
  • Optical and digital signal processing
  • Optical interferometry and characterization
  • Optical information processing and information security
  • Digital holographic microscopy
  • 3-D computer vision, Machine learning/Artificial intelligence
  • Optical biosensors
  • Green Photonics
  • Optical materials
