RGB Laser Light-Source Technology
We pursue technology development with applications in LiDAR, spatial recognition, and long-distance communication in view—including our RGB combiner, which integrates red, green, and blue lasers, and our beam technology that does not spread even over long distances.
Bundle the light,
read the distance, capture the space.
Since its founding, TEKJP has been engaged in the development of laser light-source modules.
Our RGB combiner and non-diverging beam technology. These proprietary technologies hold potential for application in new fields—extending the range of LiDAR, terrain scanning from the air, long-distance optical communication, and more.
Proprietary technologies TEKJP holds
TEKJP holds several patented technologies relating to laser light sources. Two stand out: combiner technology that treats RGB lasers as a single beam of light, and beam technology that does not spread even over long distances. With these two as our axes, we look toward applications in spatial recognition and long-distance measurement.
RGB combiner
Laser light emitted from independent red, green, and blue light sources is directed straight into a PLC (Planar Lightwave Circuit) chip through our proprietary alignment technology.Inside the chip, the waveguide combines it into a single beam of light for output.A complex optical system that conventionally combined multiple mirrors and lenses is consolidated onto a single chip—achieving dramatic miniaturization and weight reduction.
Patent
A combining technology that applies a planar lightwave circuit (PLC) to generate white light from red, green, and blue light sources.
We developed our own design tool to optimize the shape of the PLC, achieving a combining device with markedly higher light-utilization efficiency—more than double that of conventional methods (Patent No. 7629251).
Non-diverging beam technology
Through a proprietary optical design using an axicon element, we generate a "non-diverging beam" that can illuminate over long distances while maintaining energy density.
Applications are anticipated in LiDAR, long-distance measurement, long-distance optical communication, and more.
Patent
A high-efficiency, narrow-diameter beam-generating optical system that applies an axicon element to shape incident light into a ring, making 100% of it usable (Patent No. 7154669); and an ultra-compact, narrow-diameter beam-generating optical system that uses the virtual image of a line light source to generate a beam of infinite length (Patent No. 7266348).
Potential applications
Non-diverging beam technology enables use over longer distance scales than conventional laser applications. TEKJP is exploring the feasibility of implementing this technology with three areas of application in view.
VISION 01
Extending the range of autonomous-driving LiDAR
In the LiDAR used for autonomous driving, capturing distant objects with high accuracy is essential. By suppressing beam divergence, there is potential to measure stably over greater distances.
VISION 02
Terrain scanning from the air
Mounted on a drone or similar platform and aimed from the air toward the ground, the beam could be used to scan wide areas of terrain with high accuracy. Applications are anticipated in technologies that efficiently capture large areas—surveying, infrastructure inspection, assessing disaster situations, and more.
VISION 03
Satellite-to-satellite communication
If a beam can be kept narrow even over long distances, it could also be applied to optical communication between satellites. Drawing on highly directional laser light, we anticipate its development as a new means of communication in space.

We're looking for people to build with us
We are hiring engineers who bring depth in a specialized field—circuit design, embedded software, power control, data control—while also being willing to step into adjacent areas. If you want to build things that actually work with your own hands, from design through implementation to verification, we'd love to talk with you.
