本文论述新的p-i-n-FET光接收机,该机灵敏度高、没有信号积累、动态范围大,不会被目前的光发射机所饱和。应用细线条的NMOS、CMOS、或GaAsIC工艺,就能实现其集成化,它适用于闭路设备、局部地区网络和数据通信以及长距离传输。也可以把它们设计为比特率超过1Gbit/s的接收机,以用于大容量的通信系统。它们还能制作在具有其它系统功能的同一IC上,例如单片光波再生器和光调制-解调器,以及带有片上光通信端口的微处理器。

This article discusses the new p-i-n-FET optical receiver, the high sensitivity of the machine, no signal accumulation, dynamic range, will not be saturated by the current optical transmitter. It can be integrated with fine lines of NMOS, CMOS, or GaAsIC processes for closed-circuit equipment, local area network and data communications, and long-haul transmission. They can also be designed as receivers with bit rates over 1Gbit / s for use in high-capacity communication systems. They can also be fabricated on the same IC with other system functions, such as monolithic lightwave regenerator and light modulator-demodulator, and microprocessors with on-chip optical communication ports.
