▲ [14p-B409-15] Numerical Simulation on Wavelength Characteristics of an Optically Amplified Feedback Circuit for Multi-Wavelength Sensing Applications
Keywords:optical communication, optical measurement, optically amplified feedback circuit
High-precision sensing of optical power is an important technology in photonics applications such as optical measurement and optical communication We have proposed an optical amplifier feedback circuit (OAFC) method as a new method of photodetectors that can achieve remarkably high precision, that is, high resolution of optical power sensing. Then, we are studying for clarifying the performance of the OAFC. In this study, we report that the proposed method achieves about 142 times higher accuracy (about 1/142 of the resolution) compared with the conventional method without OAFC using numerical simulation.
