Abstract(in English) | We are developing a two-tone light source as a measurement instrument of photodetectors. The two-tone light source can generate two lightwaves whose frequency difference is tunable, and the power and polarization of them are equal, however the absolute optical power of the source is not sufficient. Optical amplifier would increase ASE noise, which results in the measurement accuracy degradation. Optical injection locking technique can be used to amplify the optical power without significant noise. In this paper, we will report on our results of optical injection locking experiment, by using the two-tone light source as a master laser and Fabry-Perot lasers as slave lasers. The two-tone optical signal is amplified in 17.5dB and the RF signal power from PD is increased with 34.7dB. However, it is also revealed that the RF signal was affected by unwanted pulse signal, which degrade the spectral purity. |
