The requirements for an optical sensor are high: the sensor should be reliable, quick, and
simple, and all these features must be provided at ultralow fabrication costs. The …

The ultrashort, ultrahigh intensity pulse laser has been fully developed in past three
decades. Chirped pulse amplification (CPA) system plays an important role in the …

In recent years, multi-band perfect absorbers have great advantages in spectroscopy,
infrared detection and other fields. Here we propose and use the finite-difference time …

Achieving efficient, accurate, label-free, and real-time biodetection is urgently required;
hence, we propose a miniaturized, easily integrated, high-sensitivity plasmonic metamaterial …

In this study, the finite‐element method is used to numerically calculate a photo‐thermally
induced reconfigurability in a 1D gold grating structure filled with the phase change material …

Plasmonic enhancement of nonlinear light–matter interaction can be achieved via dedicated
optimization of resonant plasmonic modes that are spectrally matched to the different …

Plasmonic nanostructures with large local field enhancement have been extensively
investigated for sensing applications. However, the quality factor and thus the sensing figure …

Optical biosensors provide important opportunities and have broad application prospects in
biomedicine, disease diagnosis, pharmaceutical, and other fields. In this paper, a reusable …

This thesis focuses on design and demonstration of read-out systems based on guided
