Exceptional Point Dynamics in Photonic Time Crystals for Enhanced Optical Sensing
Saurabh Mani Tripathi, Shalini Kumari, Krishnan Kundan +1
Exceptional points (EPs) in non-Hermitian photonics offer singular sensitivity enhancements but have thus far been realized almost exclusively in spatially engineered platforms wit…
Fiber Bragg Grating Sensors with Enhanced Sensitivity for High-Precision Multi-Parameter Detection
Neha Ahlawat, Saurabh Mani Tripathi
Exceptional points (EPs), intrinsic to non-Hermitian systems, exhibit singular spectral responses with extreme sensitivity to external perturbations, offering new opportunities for…
Simultaneous existence of ultra-high and ultra-low spectral sensitivity for Directional Couplers
Garima Bawa, Indrajeet Kumar, Saurabh Mani Tripathi
We present the experimental evidence for the existence of two exciting wavelengths, termed critical and cross-over wavelength in the transmission spectrum of fiber-optic directiona…
Ultra-high Sensitive Surface Plasmon Resonance Based Sensor with Dual Resonance
Indrajeet Kumar, Ranjeet Dwivedi, Saurabh Mani Tripathi
We show that for the optimized angle of incidence, the SPR based optical sensors exhibit dual resonance in the near-infrared region around which the sensor becomes exceptionally hi…
Single-Multi-Single Fibre Optic Structure Based Water Depth Sensor
Garima Bawa, Krishnendu Dandapat, Gyanendra Kumar +2
We propose and demonstrate a technique easy to fabricate and measure water depth based on selective mode excitation using single-multi-single (SMS) mode structure. The high extinct…
Ultra high sensitive long period fiber grating based sensor for detection of adulterator in ethanol
Krishnendu Dandapat, Indrajeet Kumar, Saurabh Mani Tripathi
An ultra-sensitive sensor based on long-period fiber graings (LPFGs) has been fabricated for the detection of methanol and water content in ethanol. Our sensor is very compact in s…
