The present invention relates to a reflective semiconductor optical amplifier package that can amplify the optical signal in a passive optical network, may be used in a variety of situations in a passive optical network, it is compact and easy to install and has a low price advantage.
Reflective semiconductor optical amplifier of the present invention packages are reflective semiconductor optical coupled to the upper side of the heat radiating TEC element, the TEC element to be formed on the upper surface of the base substrate, said base substrate having a when opposed to the upper surface and the upper surface amplifier, TO- can and the shield and the amplification region of the opening that is coupled to an upper surface of the base plate receiving the TEC element and the reflective semiconductor optical amplifier, and having an opening for inputting and outputting the optical signal to the top surface comprising a plurality of lead wires coupled to the shield layer that transmits an optical signal to be amplified and the other surface of the base substrate from the semiconductor optical amplifier amplifying region for amplifying the optical signal input is formed by a plurality of material layers, the amplification It is formed at one end of the anti-reflection coating face and the other end region of the amplification region which transmits an optical signal as the amplification region And forming the coating comprises a reflective surface for reflecting an optical signal having passed through the amplification region.
