ROHM develops and supplies LEDs, Fabry-Perot laser diodes, and VCSELs that are being adopted in laser printers, robot vacuum cleaners, and more.
At the same time, we have engaged in research and development of VCSEL module technology to achieve higher output and maximize the performance of VCSEL elements by leveraging expertise garnered from commercializing optical device-equipped products.
ROHM is developing feature-rich laser light sources by applying the above-mentioned technology to the laser light sources and elements created during R&D, contributing to higher accuracy spatial recognition and ranging systems.
This new technology makes it possible to modularize the VCSEL and MOSFET elements into a single optimized package. To maximize element performance, the parasitic inductance between elements (which is proportional to the circuit wiring length) is minimized, enabling high-speed drive and higher output. This allows users to achieve both short pulse drive (under 10ns) that reduces the effects of external noise from sunlight along with approx. 30% higher output over conventional non-modular solutions.
What’s more, this technology not only reduces circuit design load and footprint with the monolithic form factor, but also contributes to greater power savings by improving drive efficiency through high-speed drive and higher output (enabling faster operation at lower voltages).
