H：High Quality / High Efficacy / High Performance   L：Laser   J：Just Do the Right Thing！Just Do It！

HLJ was established in 2001. Through many years of dedication to the field of VCSEL technologies, HLJ has grown into a fully fledged and professional manufacturer of photoelectric semiconductors with several breakthroughs in the manufacturing processes, therefore, HLJ is not only always in the leading position of the industry, but also able to provide high speed and high-powered product.

Furthermore, by owing the most advanced technics of upstream MOCVD epitaxy and midstream chip manufacturing processes, having the independent R&D, mass production capability, and reliability testing services, HLJ has become one of the few vertical integrated companies in Taiwan.
