The Hamamatsu Photonics infrared LED is a high-speed LED developed for optical data links using PCF200 fibers. Infrared LED uses a non-confined structure chip that does not show the abrupt deterioration often encountered in some types of confined chips, thus providing high reliability over extended operation time. The optical output at the fiber end usually tends to vary due to non-uniform LED chip thickness. Infrared LED minimizes this problem by using a light condensing reflector with a slight matching offset from the chip. This widens the fiber input beam profile so fine adjustment of the optical axis is not required.
