Integrating optical semiconductor technology of the highest level, over 40 years

Beginning with the acquisition of Hitachi’s optical semiconductor business in the late 1970s, Ushio has made a habit of tracking down the brightest and best in the business. By unifying the abundant experience commanded by each acquired entity, Ushio has built an advanced SSL division.

With roots stretching back over 100 years, Ushio was incorporated in 1964 and has since established itself as a global lighting specialist and pioneer of ultraviolet (UV), visible, and infrared (IR) lighting applications.

From humble beginnings in Japan, Ushio has concentrated on applying light to life sciences, visual imaging, and electronics. The global group has grown to 5,590 employees across 57 international locations, with major offices serving customers in Asia, EMEA, and the Americas.

The origin of Ushio’s LED business began as Epitex Inc., which was established in 1989. The first Epitex product was the highly-coveted, silicon carbide (SiC) blue light emitting diode. The primary company focus later turned to high-speed, high-power IR LEDs.

In 2008, Ushio acquired Epitex to strengthen its ‘LEDs for OEMs’ business and, in 2016, would go on to merge Epitex with the laser diode division acquired from Hitachi. This brought Ushio’s LED and laser technology under one roof for the first time.

By mid-2014, Ushio had taken over Oclaro‘s industrial semiconductor business, which included the manufacture of LEDs & red, violet, and infrared laser diodes. This led to the establishment of Ushio Opto Semiconductor Inc. (UOS).

In 2020, Ushio’s primary business absorbed the SSL division at UOS to achieve its end goal of becoming a one-stop lighting solution provider. This business integration has enabled Ushio to respond quickly and accurately to the varied needs of our customers, the evolving business environment, and is expected to further accelerate the expansion of Ushio’s light source business. In the same year, Ushio completed development of the indium gallium arsenide phosphide (InGaAsP) Epitex D Series, which realized the highest ever output power and efficiency in the world for an SWIR LED.

Ushio’s all-encompassing expertise in the SSL field brings various opportunities to customize chip and packaging technologies, such as the chip design, epitaxial growth, device process, optical design, thermal management, and electrical & mechanical design.

Beyond solid state lighting, Ushio has more than half a century of experience in the manufacture and customization of optical devices and technologies. With this unrivalled knowledge and the willingness to sit down with customers to find the most suitable, bespoke solution to their needs, Ushio has been established as the trusted partner of companies and clients across the globe.
