Novel biosensor for detecting Hemoglobin and its oxidation state based on nonreciprocity in a coupled waveguide system

Olivier Martin, Shourya Dutta Gupta

We study the reflection of a tightly focused Gaussian beam off a near symmetric resonant tunneling structure comprising two identical coupled waveguides. The coupled waveguides are loaded on each side by a spacer layer and a high index prism. Reflection of ...

Ultrasensititve system for the real time detection of H2O2 based on strong coupling in a bio-plasmonic system

Christian Santschi, Olivier Martin, Shourya Dutta Gupta

We theoretically investigate the dependence of the different parameters of an optical biosensor for the detection of Hydrogen peroxide (H2O2) based on absorption enhancement of Cytochrome c molecules near gold nanoparticles. H2O2 is a major reactive oxygen ...

Controllable coherent perfect absorption in a composite film

Olivier Martin, Shourya Dutta Gupta

We exploit the versatility provided by metal-dielectric composites to demonstrate controllable coherent perfect absorption (CPA) or anti-lasing in a slab of heterogeneous medium. The slab is illuminated by coherent light from both sides, at the same angle ...

Coherent perfect absorption mediated anomalous reflection and refraction

Olivier Martin, Shourya Dutta Gupta

We show bending of light on the same side of the normal in a free-standing corrugated metal film under bidirectional illumination. Coherent perfect absorption (CPA) is exploited to suppress the specular zeroth order leading to effective back-bending of lig ...

Strongly coupled bio-plasmonic system: Application to oxygen sensing

Olivier Martin, Shourya Dutta Gupta

We investigate theoretically the strong coupling between surface plasmon resonances (SPRs) and absorption bands of hemoglobin. When the surface plasmon resonance spectrally overlaps the absorption bands of hemoglobin, the system is strongly coupled and its ...
