“…6,7 In the previous literature, the same advantages of silicon photonics have been considered in designing and modeling different sensors/ biosensors based on the variation of RI. [10][11][12][13][14][15] From the previous literature, the change in water concentration changes the RI of plasma, and the change in the RI of plasma changes the RI of blood. When the ribonucleic acid particles are increased in the infected cells compared with uninfected cells; this leads to the change in the RI in the nucleus and can be used as an indicator for detection.…”

“…[8][9][10] The proposed work is based on the spectrum analysis, which considers the variation of resonance wavelength. [11][12][13][14][15] In this paper, detection of the bacterial cells is performed using the well-established concept of RI change. The RI of a cell is different for unaffected and affected bacterial as well as viral cells.…”

Our proposed work analyzes and models the photonic crystal (PhC)-based elliptical ring resonator for detecting viral and bacterial infections. Optical sensors show extreme results as sensing devices. So, they are broadly accepted in the medical field for the rapid and effective diagnosis of diseases. Optical biosensors are designed to detect cancer, malaria, typhoid, tuberculosis, etc. The principle behind the working of optical biosensors is a shift in the peak resonance wavelength corresponding to the small changes in the refractive index values. Due to the rapid mutation and replication of viral pathogens in the human cell nucleus, there is high demand for sensors that provide accurate results for viral and bacterial diseases in seconds. Hence, optical biosensors can give results in a short amount of time with a high sensitivity. The proposed sensor achieved a high sensitivity of 881.25 nm∕RIU for tuberculosis and 555.55 nm∕RIU for hepatitis B. The quality factor and figure of merit is also calculated, and their values come out to be 624.37 and 346.38, respectively, in the case of typhoid and Bacillus cereus. The platform used for simulating the analytes is the finite-difference time-domain.

“…Ring resonators are one of the important blocks in optical integrated circuits and are widely used in applications such as filters, wavelength demultiplexers, switches, logic gates, and sensors in various configurations [34,35,[37][38][39][40][41][42][43]. Electromagnetic energy whose wavelength matches the resonant wavelength is trapped in the ring and can be filtered to a waveguide coupled to it.…”

A novel plasmonic lens based on a metal–insulator–metal bus waveguide coupled to a ring resonator is proposed and numerically investigated. The inner edge of the ring resonator was perforated with nanogrooves so that light emitted by these nanogrooves was sharply focused at the center of the ring. The structure relies on interference and resonance theory. The principle of the lens can be extended to a device 1 × N demultiplexer as well as a 1 × N power splitter. These functionalities were validated through finite element method simulations. Results show that the lens had a sharp focus, without any smearing, and a full width at half maximum (FWHM) intensity of around 240 nm. For the 1 × N demultiplexer, the selectivity was high with an FWHM bandwidth of less than 20 nm and crosstalk of less than − 10 dB, whereas the 1 × N power splitter had a narrow bandwidth and was able to split power into N equal parts with negligible imbalance. The proposed focusing structure is compact, and the simulation results show that the structure performs the various functionalities with high efficiency. Due to this, these structures will be of utmost utility in future all-optical signal processing systems.
