Abstract

We designed and constructed two novel fiber optic devices that have never been revealed before. One is a wavelength-selective optical router, and the other is a wavelength-selective retroreflector with a bypass fiber channel. They find usefulness in many applications, especially in fiber amplifier, fiber-optic communication, and fiber sensing. To prove their effectiveness, we built a single-stage, two-pass fiber amplifier system composed of these two components. The fiber amplifier yielded an unprecedent 47 dB gain with less than - 23 dB amplified spontaneous emission. The amplifier also possesses a very wide input signal dynamic range and very high output saturation limit. It can be operated in either CW mode or pulse modes.
