At the Photonics Laboratory in IIT Bombay, we are developing various photonic devices based on different spectroscopic techniques. They are tailored for various opto-electronic and sensing applications in the agricultural, healthcare and environmental sector. One such device is the low cost polymer based multi-modal / multi-spectral wide band MEMS photonic sensing platform
Multispectral
■ Photoresponsivity / photoconductivity of single device ranges from UV-visible to mid-infrared
Multimodal
■ Can be used as photo-detector or photonic sensor Salient features
■ Low dark current
■ Room temperature operation
■ Fabrication process CMOS / MEMS compatible
■ Low cost pristine polymer; No doping
Applications
■ On-chip general platform: Ready to incorporate in any spectroscopic detection such as:
‒ Absorption spectroscopy
‒ Reflectance spectroscopy
‒ Transmission spectroscopy
