We present a simple and practical strategy that allows to design high-efficiency grating couplers. The technique is based on the simultaneous apodization of two structural parameters: the grating ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

A research team has fabricated a subwavelength grating from an epitaxial molybdenum diselenide (MoSe2) layer roughly 42 nanometers thick and measured optical confinement consistent with a bound state ...

When it comes to baking with chocolate, a box grater is truly a baker's best friend. Whether you're shaving a sweet garnish over hot chocolates and lattes, grinding up a good bark for your black ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...
