Peak reflectivities of up to 99% have been achieved in the visible spectrum. FBGs in the visible spectral range require structure sizes in the sub 100 nm scale. Potential applications are in the field of laser and sensor technology.
From vibration to spectrum VIS/NIR short wavelengths are found in UV/VIS/NIR spectroscopy, where UV/VIS/NIR stands for Ultraviolet/Visible/Near Infrared, which already gives an indication of the range of application in the measurement of light spectra from 175 - 3300 nm. The background of NIR...
Thevisible spectrumis the portion of the largerelectromagnetic spectrumthat we can see. As[link]shows, the electromagnetic spectrum encompasses all of the electromagnetic radiation that occurs in our environment and includes gamma rays, x-rays, ultraviolet light, visible light, infrared light, microwave...
Wavelengths of Light and Colors Visiblelighthas wavelengths between roughly 400 nm and 750 nm; there is alsoinfrared lightwith longer wavelengths andultraviolet lightwith shorter wavelengths. As such wavelengths are rather small, light exhibits much weakerdiffractioneffects than sound waves, for example ...
In the pursuit of free-space optics with the benefits of large space-bandwidth product and massive parallel operations, here we design and fabricate a near-visible-wavelength etch-free metasurface with minimized fabrication defects and experimentally demonstrate a million-scale ultrahigh-Q resonance. A...
The Pr3+ ion doped aluminosilicate glasses present strong absorption at visible wavelengths between 440 and 500 nm which gives rise to intense emission in the visible spectrum from 570 to 660 nm. The visible luminescence spectra under excitation at different pump wavelengths and the lifetime of ...
quantum computing and communications to store data in qubits. Quantum applications currently depend on bulky, powerful lasers that limit their use outside of the laboratory. Access to the green gap wavelengths could also help bring nonlinearnanophotonics and its many advantages to the visible spectrum...
The thermal radiation of shorterwavelengthsthan the visible are called ultraviolet. 波长短于可见光的热辐射称紫外线. 辞典例句 For longerwavelengthsa number of extrinsic photoconductive devices exist. 对于更长的波长,有许多非本征光电导器件可用.

Visible lightis a range ofelectromagnetic radiationthat can be detected by thehuman eye. Thewavelengthsassociated with this range are 380 to 750nanometers(nm) while thefrequencyrange is approximately 430 to 750 terahertz (THz). The visible spectrum is the portion of the electromagnetic spectrum betw...
