It is widely assumed that diffraction places a limit on the smallest features that can be produced by light-based fabrication techniques, such as photolithography. This limit is typically about ...

The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...

Abstract: Ensuring adequate wireless coverage in upcoming communication technologies such as 6G is expected to be challenging. This is because user demands of higher data rate require an increase in ...

Abstract: The output coupler free external cavity spectral beam combining structure uses the beam along 0-order and 1-order diffraction direction as the feedback light beam to realize the wavelength ...
