An electronic amplifier device is recognized as the most important device for signal recovery in long distance transmission. Basically, such a device can be constructed in various types and forms, from which the same specification is the signal amplification, where the other properties such as bandwidth, response frequency, size, and materials etc. are also included. Nowadays, the large demands of using the small scale device within the scale of few micrometers have the key issue of device fabrication, which has shown the rapidly developed. Recently, a group of researchers has shown the very interesting concept of signal recovery that can be formed by using the small scale device, where the light signal in the form of a photon (coherent light) can be functioned as self-pumping (recovery) within the small circular-like path propagation.
