Optoelectoronics Device Technology
VCSEL (Vertical Cavity Surface Emitting Laser)

High density two-dimensional surface-emitting laser
array with highly uniform optical characteristics

With a two-dimensional array of 32 channels, this surface-emitting semiconductor laser is used as a light source in the scanning-type exposure devices of copy machines. Our in situ monitoring system maintains a uniform active area diameter and holds variations caused by optical output characteristics to 1% or less.

In situ monitoring system

This system employs a Fujifilm-developed system that utilizes changes in the light reflectivity on the wafer’s surface to make observable the active area diameter, which is invisible to the naked eye.

4K HDMI/IP Optical Transmission System

The world’s first system that enables simultaneous
transmission of 4K video, audio and LAN
communications data over long distances

This system allows for simultaneous transmission of 4K video, audio and local area network (LAN) communications data over distances as long as 800 meters, thereby supporting the construction of systems using simple cabling that integrates advanced video and network devices.

VCSEL Data Transmission

Fuji Xerox has achieved fiber optic data transmission by applying its proprietary surface-emitting semiconductor laser technology called VCSEL*, which was originally developed for color multifunction printers.
