英文摘要	PURPOSE: To obtain a coating that has a low-level reflection factor and a sufficient stability and an improved reproducibility by performing coating with hafnium oxide in a light-electricity device with a facet having a reflection- preventing coating for transmitting light radiation. CONSTITUTION: Limiting layers 11 and 12 formed on a substrate 10 made of InP are formed by p-and n-type InP, respectively, and an active layer 13 made of phosphor indium gallium arsenic semiconductor is arranged between the limiting layers 11 and 12 and has a higher refractive index than the two limiting layers 11 and 12. The two edge-part facets of an amplifier are coated with reflection-preventing coatings 14 and 15 formed by hafnium oxide with a reflective index of 87-2.00 and a packing density of 0.91, thus achieving a coating that has an allowable low-level reflection factor, a sufficient stability, and an improved reproducibility.
