The “Optical Art” led by optical modulators

With the further development of science and technology, optical modulators will also play an important role in multiple fields such as holographic projection and display, optical data storage, optical communication, computational imaging and machine vision.

Frontier Applications in Optics

1.Optical communication field

With the development of communication technology, optical modulation has become the cornerstone of modern optical communication systems, and its development directly affects the speed and bandwidth of data transmission. With the launch of 5G and the future 6G networks, the demand for high-speed and large-capacity data transmission is increasing day by day. The advancement of optical modulation technology will directly promote the leapfrog development of information technology. Thanks to the high energy and high frequency characteristics of photons, optical modulation technology plays a key role in the field of optical communication. By precisely controlling the phase, amplitude or polarization state of light, optical modulators can encode signals to achieve high-speed and high-bandwidth data transmission. When light waves pass through the modulator, the modulator dynamically changes the characteristics of the light waves according to the transmitted data. This precise modulation enables multiple signals to be transmitted simultaneously in the same optical fiber, greatly enhancing the information carrying capacity and efficiency of the communication system.

2.Computational imaging and machine vision field

The application of optical modulation technology in computational imaging and machine vision has significantly changed the way images are acquired and analyzed. This technology enhances the quality and information content of images by precisely controlling the phase, amplitude or polarization state of light, thus achieving breakthrough progress in multiple industries. Computational imaging is a technology that combines optical design and post-image processing algorithms to improve image quality and solve traditional imaging problems. In this process, optical modulators such as SLM and DMD play a crucial role. They can dynamically adjust the propagation characteristics of light waves, such as achieving wavefront coding by changing the phase distribution of light, or adjusting the amplitude distribution of light to achieve high dynamic range imaging of the scene. In machine vision systems, optical modulation technology is employed to achieve more precise scene capture and object recognition. By using a light modulator to precisely control the incident light, the machine vision system can extract more scene information under complex lighting conditions, improving the contrast and resolution of the image.

Optical modulators are like magic wands in the hands of magicians, not only demonstrating astonishing magic in modern communication, computational imaging and photoelectric systems, but also opening up doors of infinite possibilities for the future. Imagine that it is like a precise tuner, capable of adjusting the “notes” of qubits, making quantum effects and optical phenomena display more charming melodies. It is also a “magician” of microelectronics and nanotechnology, capable of pushing the utilization rate of materials to the extreme and making the production process as efficient as an automated magic array. With the advent of 5G and even 6G networks, optical modulation technology acts like a rapid messenger, fulfilling our desire for high-speed and large-capacity data transmission. Despite the high costs, complex systems and traditional industry “established challengers” on its development path, through continuous technological progress and “alliances” among disciplines, all these problems will be overcome one by one. In the future, optical modulators will become the engine of change and convenience, leading revolutionary changes from scientific research to healthcare, from industrial production to new energy development, and even in the fields of information technology and military security.
