Our researcher proposed and verified the system for three-dimensional incoherent imaging using spiral rotating point spread functions created by double-helix beams that exhibit higher focal depth than direct imaging systems. I firmly believe that the current study will open a pathway for implementing different incoherent exotic beams and structured light for multidimensional and multispectral imaging technologies.

Metalens design with silicon cross-shaped meta-atoms that form two-polarization dependent focal points was developed. The dielectric metalens with controlled functionality operates in a visible regime to generate subwavelength light intensity distributions with an extended depth of focus, which is highly desirable in numerous applications that can not be achieved by mono-polarization.

Robust demultiplexing of OAM beams of different values into various geometrical configurations over a broad wavelength range was demonstrated. The proposed approach paves a way to reduce the cost of the commercial OAM modes-based communication systems and projects a simple method for increasing the number of channels in the communication system over free-space or fiber links with minimal intermodal crosstalk.

Research project “Design of Long-Distance High Data Rate Laser Optical Communication Systems” in collaboration with the State Education Development Agency

Laser communication has potential advantages in comparison to radio frequency communication for space vehicles. The project team developed the concept of the bidirectional communication system for free space (FSO) laser communication links from space terminals (ST) at low Earth orbit (LEO) nano-, microsatellites with emphasis on CubeSat or Unmanned Aerial Vehicle (UAV) to transportable or to stationary positioned optical ground based terminal (GT) to achieve the high data rate communications.

Bidirectional space to ground
laser communication system for cubesat

Laser communication has potential advantages in comparison to radio frequency communication for space vehicles. The project team developed the concept of the bidirectional communication system for free space (FSO) laser communication links from space terminals (ST) at low Earth orbit (LEO) nano-, microsatellites with emphasis on CubeSat or Unmanned Aerial Vehicle (UAV) to transportable or to stationary positioned optical ground based terminal (GT) to achieve the high data rate communications. 

Very accurate pointing and tracking capability will be provided by options of optical auto-tracking for both ST and GT. This capability will provide fast moving of flying platforms with very precise visible movement tracking of their optical axes of telescopes and their optical alignment. Such improvement will allow optical transmission of data over a long distance while requiring fewer resources from the hardware of flying platform ST. These solutions give significant advantages compared to existing solutions. Our innovative diffraction resolution without aberration of the optical system with broad spectrum band will be used for the ST during of work of transmission, receiving, and video optical channels. The optical systems of GT embedded in the lightweight 2-axes alt-azimuth mount with enhanced turning range will allow smooth, high-speed tracking without any gaps at zenith. All optical system axes of GT and the alt-azimuth mount axes are controlled by an auto-collimator having unique auto-adjustment feature. The innovative stationary positioned GT is also proposed.

Optical communication ground station

Optical links are the future of satellite communications. Optical communication in space opens virtually unlimited capacities without regulations. By using lasers, satellite optical communication has a readily available frequency band and can transmit with higher power efficiency and with smaller and lighter terminals. Thus, it is expected to be a key technology to support the future satellite communication. For a given mass, power consumption and volume, laser communications can offer an increase in bandwidth over classical RF technology allowing for a variety of new options.

We are a few years away from the mass adoption of optical communications ground terminals, Photonic can propose the technology for customers that wish to explore it further.

Photonic has invented & developed a revolutionary connectivity technology for communication with satellites in different orbits (LEO/MEO/GEO) and can be used for terrestrial data networks. This fundamental technology solves the problem of capacity limitation of satellite communication, crucial for this massive emerging market, while guaranteeing a breakthrough robustness to jamming & interferences, the ultimate long range with a very low energy consumption from the ground to any high-flying platform.
