| titleOfInvention | Frequency modulation response evaluation method and evaluation apparatus |
| abstract | (57) [Abstract] [Objective] To provide a frequency modulation response evaluation method and an evaluation device capable of measuring the frequency modulation response characteristic of a semiconductor laser up to a high frequency region by using a low speed optical receiver without using a high speed optical receiver. To do. [Structure] Set the modulation frequency of the semiconductor laser to the required value, Next, the modulation current is changed to set the modulation current so that the size of the ± 1st-order sideband is a specific value of 0.41 with respect to the size of the carrier. By an evaluation method including a procedure of calculating the frequency sensitivity from the frequency modulation degree and the modulation current defined correspondingly, and by adjusting the modulation current value for frequency-modulating the semiconductor laser, An evaluation apparatus having a configuration for detecting a spectrum of ± first-order sidebands in which the ratio to the carrier size in the optical spectrum is a specific value of 0.41. |
