A New Type of Laser Pointer Based on Unconventional Physical Phenomena

Researchers at the University of California, San Diego have demonstrated the world’s first laser pointer based on an unconventional wave called continuous bound state (BIC) in physical phenomena. This technology can completely change the development of surface laser technology, making them more compact and energy-efficient to achieve applications in the field of communication and computing. The new BIC laser can also be further developed into high-power lasers used in industry and national defense.

Lasers are currently everywhere in the world, ranging from everyday simple laser pointers to complex laser interferometers to detect gravitational waves. Our current research will affect the application of lasers in many fields. He is a doctoral student in the Department of Electrical Engineering at the University of California, San Diego and the first author of the research. Because of their unconventional characteristics, BIC lasers can provide unique, unprecedented performance that has not been achieved with existing laser technology. He is a professor of electrical engineering at the Jacobs College of the University of California, San Diego.

For example, BIC lasers can be easily adjusted to emit beams of different wavelengths, and medical green laser pointer can accurately target tumor cells without damaging normal tissues. BIC lasers can also produce beams that can emit specially designed shapes (such as spirals, donuts or bell curves) called vector beams, which can make increasingly powerful computers and optical communication systems carry up to 10% more information than existing ones. Times more.

In today’s mobile phones, computers and astronomy, the light source is the key component of optical data communication technology. In this work, we proposed a new light source that is more efficient than the lasers used today in terms of power consumption and speed. He is a doctoral student in the electrical engineering department of Kanté laboratory and a research collaborator.

The continuous bound state (BICS) phenomenon was predicted to exist in 1929. The properties of continuous bound states are still restricted or bound in an open system. The traditional waveform will escape in an open system, but the continuous bound state will not escape outside the norm, even though the escape path is open.
