A compact, low input power optical bistable device, combined with photodetector and optical fiber directional coupler and semiconductor laser diode, was presented.
In this paper, a novel coupler-holographic coupler bet-ween light emitted diode (LED) and fiber is proposed. The theoretical, design is carried out. The method and results of design are given.

It acquired coupling power 7.23w and coupling efficiency better than 70%, when the fused side-coupler was pumped by a high-power laser diode arrays in experiments.
