Monitoring changes in water temperature and pressure at the seafloor can improve understanding of ocean circulation, climate, and natural hazards such as tsunamis. In recent years, scientists have ...

Conventional structural color sensors with an even thickness can hardly detect tiny structural changes caused by analytes at extremely low concentrations. Herein, we construct a gradient protein ...

However, diode lasers emit broadband radiation. For this reason, the researcher developed a concept to reduce the bandwidth and stabilize the wavelength of the laser radiation. Once again, a directly ...

Z-domain model of fiber Bragg grating is developed, and its performance analysis is presented in this letter. The developed mathematical model is used for the evaluation of reflection and transmission ...

Our proprietary process encapsulates the grating structure in a robust package, facilitating easy cleaning and handling during system build. We can create both broad bandwidth and high dispersion ...

We present a new, direct laser-written integrated Bragg grating spectrometer, with large bandwidth due to the large blaze angle of the grating. Integrated cost-effective solutions to spectral ...

Waveguide gratings are one of the key optical dispersion handling devices and are highly desired for many on-chip photonic systems. However, most of the previously reported waveguide gratings require ...

The sensor features two orthogonally crossed microfiber Bragg gratings, using parallel, micro-Co 2+ -doped optical fibers, which allow detection in a figure 8 pattern with 1.57 millivolts per degree ...
