Method of and apparatus for controlling wavelength variable semiconductor laser without preparing a high-precision current table |
摘要 |
An oscillation state of a semiconductor laser is decided. Injection current to the first and second light reflectors of the semiconductor laser are simultaneously swept based on the oscillation state of the semiconductor laser to obtain current conditions of the injection current to the first and second light reflectors that carry out single-mode oscillation in a target wavelength. The semiconductor laser is drive controlled with the obtained current conditions.
