Patent Images
1. A wavelength controlling method of an external cavity type tunable light source, the method comprising:
- performing a first calibration of obtaining a tuning curve representing changes of a wavelength as a function of a heater power up to a wavelength range where the external cavity type tunable light source is tunable;
performing a second calibration of obtaining a detuning curve of the tunable wavelength range; and
setting a wavelength by performing a wavelength locking.
