“…A simplified vision of waveguide sensing provides two options, since the waveguide can be used either as a probe or as a source. In the first case, the sensing or detection mechanism is often evanescent [ 146 , 147 ]. However, specific waveguide configurations may allow interaction between the analyte and the core propagating light, such as in the cases of slot [ 148 ], and anti-resonant reflecting optical waveguide (ARROW)-based sensors [ 149 ].…”

The prevalent nature of micro and nanoplastics (MP/NPs) on environmental pollution and health-related issues has led to the development of various methods, usually based on Fourier-transform infrared (FTIR) and Raman spectroscopies, for their detection. Unfortunately, most of the developed techniques are laboratory-based with little focus on in situ detection of MPs. In this review, we aim to give an up-to-date report on the different optical measurement methods that have been exploited in the screening of MPs isolated from their natural environments, such as water. The progress and the potential of portable optical sensors for field studies of MPs are described, including remote sensing methods. We also propose other optical methods to be considered for the development of potential in situ integrated optical devices for continuous detection of MPs and NPs. Integrated optical solutions are especially necessary for the development of robust portable and in situ optical sensors for the quantitative detection and classification of water-based MPs.

“…and developed into integrated devices and even relatively large-scale integrated circuits [ 2 ]. The development of optical devices (lasers [ 3 , 4 , 5 ], amplifiers [ 6 ], modulators [ 7 ], filters [ 8 ], waveguide circuits [ 9 ], switches, detectors, etc.) will go through a similar process.…”

Femtosecond Laser Direct Writing of Optical Overpass

With the rapid increase in information density, problems such as signal crosstalk and crossover restrict the further expansion of chip integration levels and packaging density. Based on this, a novel waveguide structure—photonic jumper wire—is proposed here to break through the technical restrictions in waveguide crossing and parallel line wrapping, which hinder the integration of photonic chips. Furthermore, we fabricated the optical overpass to realize a more complex on-chip optical cross-connection. Our method and structure promote a series of practical schemes for improving optical chip integration.
