The optical control ability of photonic crystal fiber (PCF) is a distinctive property suitable for improving sensing and plasma performance. This article proposes a dual-core D-channel PCF sensor that can detect two samples simultaneously, which effectively solves the problems of coating difficulty and low wavelength sensitivity. The PCF has four layers of air holes, which dramatically reduces the optical fiber loss and is more conducive to the application of sensors in actual production. In addition, by introducing dual cores on the upper and lower sides of the central air hole, reducing the spacing between the core and the gold nanolayer, a stronger evanescent field can be generated in the cladding air hole. The optical fiber sensor can detect the refractive index of two samples simultaneously with a maximum sensitivity of 21300 nm/RIU. To the best of our knowledge, the sensitivity achieved in this work is the highest sensitivity with the dual sample synchronous detection sensors. The detection range of the refraction index is 1.35-1.41, and the resolution of the sensor is 4.695×10-6. Overall, the sensor will be suitable for medical detection, organic chemical sensing, analyte detection, and other fields.

“…Modulation of light propagation [26][27][28] motivates different constructions of photonic structures. Strong stretching pulses are observed through the band-edge states in Fibonacci multilayers, [6,29] and the optical modes are also reported as ones with fast decay in a positional-disordered multilayer.…”

Optical systems offer rich modulation in light propagation, but sufficient quantitative descriptions lack when highly complex structures are considered since practical structures contain defects or imperfections. Here, we utilize a method combining a data-fitting method and a time-resolved system to describe light propagation near the band edges in one-dimensional structures. Calculations after optimization of the method show little deviation to the measurements.

“…Here, we propose a novel photonic crystal fiber (PCF) fluorescence sensor which is developed based on an enzymelinked catalytic reaction for high-performance detection of LA enantiomers. Owing to its unique properties, PCF opens up new applications in nonlinear devices, fiber lasers, high-power transmission, and many other fields [33][34][35][36][37][38]. In addition to guiding light in a hollow core, PCF can be considered analogous to a bundle of capillary tubes with an inner diameter of several micrometers and has several essential advantages for assaying trace-amount samples [39][40][41].…”

Graphical abstract A photonic crystal fiber (PCF)–based fluorescence sensor is developed for rapid and sensitive detection of lactic acid (LA) enantiomers in serum samples. The sensor is fabricated by chemical binding dual enzymes on the inner surface of the PCF with numerous pore structures and a large specific surface area, which is suitable to be utilized as an enzymatic reaction carrier. To achieve simultaneous detection of l -LA and d -LA, the PCF with an aldehyde-activated surface is cut into two separate pieces, one of which is coated with l -LDH/GPT enzymes and the other with d -LDH/GPT enzymes. By being connected and carefully aligned to each other by a suitable sleeve tube connector, the responses of both l -LA and d -LA sensors are determined by laser-induced flourescence (LIF) detection. With the aid of enzyme-linked catalytic reactions, the proposed PCF sensor can greatly improve the sensitivity and analysis speed for the detection of LA enantiomers. The PCF sensor exhibits a low limit of detection of 9.5 μM and 0.8 μM, and a wide linear range of 25–2000 μM and 2–400 μM for l -LA and d -LA, respectively. The sensor has been successfully applied to accurate determination of LA enantiomers in human serum with satisfactory reproducibility and stability. It is indicated that the present PCF sensors would be used as an attractive analytical platform for quantitative detection of trace-amount LA enantiomers in real biological samples, and thus would play a role in disease diagnosis and clinical monitoring in point-of-care testing.
