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 ...

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 ...

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 ...

Abstract: An imaging scanning diffraction grating suitable for the development of portable, low-cost infrared (IR) spectrometers is presented. The 2 mm-diameter resonant MEMS scanner can be integrated ...
