Spatial Light Modulator Market

Spatial Light Modulator Market Outlook (2023 to 2033)

The global spatial light modulator (SLM) market is valued at US$ 600 million in 2023 and is predicted to reach US$ 2.1 billion by 2033, expanding at a CAGR of 13.5% over the next ten years.

A spatial light modulator (SLM) is a device that modifies the amplitude, phase, or polarization of light waves in space and time. SLMs are utilized in a variety of applications, including holographic displays and liquid crystal microdisplays. An electro-optic modulator (EOM) is an optical device that uses a signal-controlled element with an electro-optic effect to modulate a light beam. The modulation can be applied to the beam's phase, frequency, amplitude, or polarization. With the use of laser-controlled modulators, modulation bandwidths in the gigahertz region are achievable.

Liquid crystal modulators are optical modulators that rely on liquid crystals. They are predominantly used for displays, although they can also be used for a variety of other purposes. A transmissive spatial light modulator, which includes a light-transmission area, consists of the following components: a transparent substrate, a pixel drive circuit located on the transparent substrate to create an area outside the light-transmission area, and a transmissive light modulation section that incorporates a micro-electromechanical element. The pixel drive circuit controls the transmissive light modulation section, which is positioned above the pixel drive circuit.

SLMs find widespread applications in holographic data storage configurations, where they are utilized to encode information into a laser beam, much like transparency does in an overhead projector. Additionally, SLMs play a crucial role in holographic display technologies. Moreover, SLMs have been employed as essential components in optical computing systems.

An optically addressed spatial light modulator (OASLM) functions by recording the image on a write beam and subsequently transferring it to a read beam. OASLMs find various applications, including image transduction, optical correlation, adaptive optics, and optical neural networks.

• The recent surge in interest in OASLMs can be attributed to QinetiQ's pioneering work on 3D displays. The company’s approach involves active tiling, wherein an image is recorded in a specific part of the device and stored, while the rest of the device is updated with new images.

The image on an electrically addressed SLM (EASLM) is formed and modified electronically, as is the case with most electronic displays, as the name suggests. EASLMs often receive input through a normal interface such as VGA or DVI. They are available in resolutions as high as QXGA (2048 x 1536).

Why are SLMs Widely Used in Holography?

“Realistic and Adaptive 3D Image Reconstruction Capability of SLMs”

Holography is a technique that enables the recording and reconstruction of three-dimensional (3D) images. In holography, a laser beam expander is split into two parts: the reference beam and the object beam. The object beam interacts with the object being imaged and the interference pattern between the object beam. The reference beam is recorded on a photosensitive medium.

SLMs are utilized in holography to control the phase or amplitude of the laser beam, which affects the interference pattern. They provide the ability to manipulate the phase or intensity of light at each pixel, making it possible to encode complex wavefronts required for 3D holographic image reconstruction. Use of SLMs allows for dynamic control and adjustment of holographic patterns, making the holographic display more versatile and adaptive.
