What is Grating or Diffraction Grating?
In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams traveling in different directions, called grating orders. The directions of these beams depend on the spacing of the grating, the incident angle, and the wavelength of the light. The wavelength dependency makes the grating act as a dispersive element and so can be commonly used in spectrometers.
Gratings can be either transmissive or reflective for incident light. Gratings can also modulate the phase of the incident light rather than its amplitude, which is called phase diffraction grating.
The efficiency of a grating is defined as how much optical power is distributed in each grating order, and it is also dependent on the polarization of the incident light.
Basically, a diffraction grating performs a Fourier Transform, separating a waveform in the time domain into a number of waveforms in the frequency domain.
Grating Manufacturing and Applications
A diffraction grating can be produced by first ruling a master grating, and then replicating this master into a large number of exact copies, called replicas, for cost savings and product consistency.
Master gratings can be manufactured using some of the following technologies:
- Mechanical ruling
- Holographic recording from photolithography
- Ion-etching of holographic master based on low-cost semiconductor technology
- micro-lithography or nano-imprinting technology
Optical gratings have applications in everywhere due to its sensitivity to wavelength and refractive index, beam splitting and phase modulation function.
- Laboratory spectroscopy systems, like spectrophotometers
- Telecommunication active & passive modules, like WDM(wavelength division multiplexer), and fiber Bragg grating filter
- Colour analysis instruments, such as colorimeter
- Biomedical devices and Life science products, such as bioanalyzers
- Analytical chemistry application
- Lasers, ultrafast and high-energy lasers
- Space flight instruments and astronomy
