1024 × 1024 Spatial Light Modulator – High-Speed Phase Modulation
The 1024 × 1024 Spatial Light Modulator from Meadowlark Optics is a high-resolution Liquid Crystal on Silicon (LCoS) phase modulator for applications where high modulation speed must be combined with high phase stability. With 1024 × 1024 pixels, a pixel pitch of 17 × 17 µm and an active area of 17.4 × 17.4 mm the SLM is particularly well-suited for demanding applications in research, photonics, and laser beam shaping.
The combination of analog data driving and specially developed LCoS technology enables high update rates combined with very low phase instability. This makes the SLM suitable for applications where rapid changes of complex phase patterns are required.
High-speed and ultra-high-speed phase modulation
The 1024 × 1024 SLM was specifically developed for applications where short liquid crystal response times are critical. Depending on the wavelength and configuration, available are high-speed and ultra-high-speed versions available.
In the ultra-high-speed configuration, for example at 532 nm, liquid crystal response times of ≤ 0.6 ms reached. Even at longer wavelengths, the system enables rapid phase changes while maintaining high phase stability.
The analog control thereby reduces the phase fluctuations that frequently occur in fast digital SLM systems and enables precise, continuous phase modulation.
High optical efficiency
With a Fill Factor of 97.2 % the SLM offers a high effective optical area. The diffraction efficiency can be achieved by an optional dielectric mirror coating be increased additionally.
Depending on the optical configuration, different AR coatings are available for the ranges 488–850 nm, 500–1200 nm, and 850–1650 nm available. This allows the SLM to be adapted to visible as well as near-infrared laser sources.
Precise wavefront control
The high phase stability makes the 1024 × 1024 SLM particularly interesting for applications where precise control of the optical wavefront is required. Typical application areas include, for example:
- Holographic projection
- Adaptive optics
- Laser beam shaping and beam steering
- Holographic optical tweezers
- microscopy
- pulse shaping
- Optogenetics
- Quantum Optics and Quantum Computing
- Optical information processing
Through programmable phase modulation, complex wavefronts can be generated and dynamically modified without moving optical components.
