“…Ultrafast ferroelectric polarization switching is also known in BTO thin films. , In a recent study, in a BTO-embedded optical microcavity, the steady-state nonlinear absorption at 532 nm showed cavity-dependent enhancement. , In general, the BTO alone has been proven to be a potential nonlinear and ferroelectric switching material, whereas the photonic structure-influenced BTO hot carrier ultrafast dynamics of electron–photon interaction is interesting and has not been explored so far. Recent reports on photonic and phononic responses of 1D photonic crystals envisaged a strong path toward nonlinear optic, refractive sensing, biological sensing, gas sensing, and optical filtering applications. − …”

The ultrafast absorption dynamics of photonic modes and enhanced features of electronic states have been demonstrated in a barium titanate (BaTiO 3 , BTO)-embedded onedimensional photonic crystal. The photonic structure has been realized as an optical microcavity, where a BTO central layer is sandwiched between two SiO 2 /TiO 2 -distributed Bragg reflectors. Angle-dependent transient absorption behavior reveals the excitedstate absorption dynamics of cavity-tuned BTO defect energies. Furthermore, the dynamic evolution of photonic minibands of both sides of the photonic cavity mode demonstrates the enormous cavity field confinement effect. The temporal evolution of nonlinear absorption dynamics is specific to cavity angle tuning and is evidenced by seven orders of two-photon absorption enhancement in BTO mid-bandgap energies. Overall, the results highlight the impact of strong optical field confinement within the BTO central layer. The simulations of spatial and angledependent localized optical field and energy deposition within the photonic structure further support the experimental findings. The enhanced features of ultrafast absorption dynamics and strong optical nonlinearities of the BTO-based active photonic structure offer a better understanding of electron−photon interaction, which paves the way for many novel nonlinear, hybrid optoelectronic, and photonic device applications.

“…This structure is unique in that it is constructed entirely of a single material. It is capable of tuning its sensitivity to detect the presence of glucose in human blood VOLUME 10, 2022 at deficient levels (g/l) using a minor variation in glucose content (g/l) [83]. The tricore PCF glucose sensor uses a triangular lattice configuration with three regional ring air holes, as shown in Figure 17.…”

This review summarizes recent advances in sensors based on photonic crystal technologies for biomedical sensing applications. Photonic crystal sensing offers enormous promise due to their clear benefits in sensitivity, stability, compactness, portability. This work discusses several photonic crystal structures, such as photonic crystal waveguides, cavities, and photonic crystal fiber for biomedical sensing applications. The uniqueness, measurement technique, and biosensing properties of each type of these structures are discussed. Furthermore, manufacturing and functionally relevant properties that include design simplicity, compactness, and multi-wavelength operation are also reviewed. They are explored, organized, and compared using the most recent related literature in this field. Finally, a brief of novel trends has been introduced.INDEX TERMS Biomedical sensors, photonic crystals, photonic crystal fiber.

“…In 2018 Natesan proposed a blood glucose sensor using a trinuclear photonic glass fiber, where a hollow channel filled by analyte acts as a liquid core and two nuclei remain considering the silicon substrate having a sensitivity of 23267.33 nm/RIU. The transmission spectrum shows a maximum wavelength shift for polarization at 470 nm [92]. This same year, Hossain presented an optimized hexagonal photonic glass fiber (PCF) geometry for the detection of glucose concentrations of 20%, 30%, 40%, 50% and 60% in water at wavelengths ranging from 1200 nm to 1600 nm [93].…”

Fiber Optic Sensors: A Review for Glucose Measurement

et al. 2021

Diabetes mellitus is a chronic metabolic disorder, being globally one of the most deadly diseases. This disease requires continually monitoring of the body’s glucose levels. There are different types of sensors for measuring glucose, most of them invasive to the patient. Fiber optic sensors have been proven to have advantages compared to conventional sensors and they have great potential for various applications, especially in the biomedical area. Compared to other sensors, they are smaller, easy to handle, mostly non-invasive, thus leading to a lower risk of infection, high precision, well correlated and inexpensive. The objective of this review article is to compare different types of fiber optic sensors made with different experimental techniques applied to biomedicine, especially for glucose sensing. Observations are made on the way of elaboration, as well as the advantages and disadvantages that each one could have in real applications.
