L8013
Easy optical axis alignment LED for PCF200 fiber data links
L8013 is a high-speed LED developed for optical data links using PCF200 fibers. L8013 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. L8013 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.
