Invention description (5) For example, metal. Metal conductors have a large number of free electrons that can be moved, so the data can only move on the same energy level, so it is not suitable for use as a receiving area. The other is an insulator, but it is not suitable because it cannot absorb the ions. Converting optical signals into telecommunications, the two high levels excite the thunder from a lower energy level to a higher energy level because the electrons are excited to the higher energy level because they are excited by the energy at the port. When electrons move to y τ at a high energy level, holes will be left in the low energy level band, and it will be easily filled by the free electrons that J: 他 可 # ^ 后 ’,,’, ”spears move. Under the foregoing limitation, 'only semiconductor systems are considered materials of 200. % &Amp; Semiconductors are intrinsic semiconductors (Intrinsic, or elemental semiconductors) and non-remaining cars ', Zeng f (Efrinsic', or compound semiconductors) whose conductivity is between conductors and non-conductors. Intrinsic semiconductors are semiconductors such as pure silicon. Extrinsic semiconductors add intrinsic impurities to change conductivity, which can be divided into negative semi-negative (n-type) and positive semiconductor (p_type). The added impurity ^ (P) can produce The excess electrons are negative semiconductors, and the added μ, such as boron (B), can generate excess holes as positive semiconductors. This phenomenon is due to the fact that the electrons inside the material are distributed in a range (energy band). The energy band that allows electrons to move freely is called the conduction band, unless it is within the conduction band. With electronic activity, matter will not be able to conduct current through the electrons. The electrons in other energy bands must overcome the energy barrier and jump to the conductance band before they can become conductive electricity. Because the energy barrier is too large, the electrons cannot jump to conductance. = Two or even an insulator; as for semiconductor (semiconductor), its energy 1 barrier is not very large, between non-conductor and conductor.

Description of the invention (6) Jia band and conduction band, and the valence band and conduction band is the so-called energy gap. To Ling Semiconductor, although sometimes its valence band is almost full, but because the energy gap is small, electrons can get enough energy to jump to the special conduction band at a certain temperature to conduct electricity.
因此，光電轉換過程係可由摻雜Ρ型雜質（p - d 〇 p i n g )以在較低能階形成較多的電洞。轉換的過程如下。在未 摻雜雜質的區域接收一具有足夠能量激發電子之光子 (photon)，電子則被吸引到與半導體相接之電極，原來 電子所留下的電洞則由P區域（p-doped region)的電子 所填滿。當P區域與N區域接觸時，將會形成一接面，其特 性類似沒有摻雜雜質之材料，因此光電轉換可以藉由特殊 結構的PN二極體來達成。 綜上所述，接收區2 0 0係採用化合物半導體作為其材 質，亦即摻入雜質之半導體。化合物半導體的優點有二， 第一，是化合物半導體的電子遷移率較矽半導體快許多， 因此適用於高頻傳輸；第二，是化合物半導體具備較佳效 率的光電轉換特性，這是矽半導體沒有的，因此化合物半 導體可運用在光電轉換的領域。Therefore, the photoelectric conversion process can be doped with a p-type impurity (p-dopio n g) to form more holes at lower energy levels. The conversion process is as follows. Receive a photon with sufficient energy to excite the electrons in the undoped region. The electrons are attracted to the electrode connected to the semiconductor. The holes left by the electrons are originally in the p-doped region. Filled with electrons. When the P region is in contact with the N region, a junction will be formed. Its characteristics are similar to those of materials not doped with impurities, so photoelectric conversion can be achieved by a special structure of the PN diode. To sum up, the receiving area 200 uses a compound semiconductor as its material, that is, a semiconductor doped with impurities. There are two advantages of compound semiconductors. First, compound semiconductors have much faster electron mobility than silicon semiconductors, so they are suitable for high-frequency transmission. Second, compound semiconductors have better efficiency photoelectric conversion characteristics. Therefore, compound semiconductors can be used in the field of photoelectric conversion.

Because the receiving end 2 i 0 receives the ^ ^ 2 signal, the optical signal must be converted to the ^: ,, " number by the receiving area 2 00. Therefore, the receiving area 2000 and the receiving end 2 10 are connected by an optical fiber / flood, so that the optical signal 100 D is transmitted to the optical signal 0 through the optical fiber 2 2 0 and consumes 200. ^^ Main receiving area In the second embodiment, the receiving areas 200 and 2 1 0 'are arranged in the system in order to receive optical signals more completely. Because of the problem of light signal and reflection, the light beam emitted by the transmitter 100 is not ready for reception by the receiver 210. Therefore, the receiver 200 can solve this problem. Since the connection = no, the light beam 100E that is not received by the receiving end 210 is received by the receiving area 2000. The light beam 100F reflected through the wall 960 can also be received by zone 2000. Please refer to "Fig. 4" for the third embodiment of the wireless signal wheel and receiving system disclosed in the present invention.

Receiving area so that the whole is received. Before the receiving end receives the signal, an attenuation condition of an optimal transmission distance is set by the end and the transmitting end. Adjust the area of the receiving area and the area to increase the signal. It is only the preferred embodiment of the invention, and is covered by the scope of the creation patent according to this creation application patent.
