Optical Semiconductor Devices


Toshiba's portfolio of optical semiconductor devices includes white LEDs, photocouplers, photorelays and optical fiber couplers (TOSLINK™).
 Toshiba offers white LEDs specifically designed for lighting applications. The latest white LED series is fabricated using a GaN-on-Si process that epitaxially grows a gallium nitride (GaN) layer on top of silicon (Si) wafers. It helps reduce the power consumption and cost of lighting equipment.
Toshiba's photocouplers have commanded the world's highest market share for four consecutive years.
They help improve the safety, cut the power consumption and reduce the size of end products.
