Abstract:
A wavelength tunable light source has a light source, a wavelength monitor circuit that receives a portion of light emitted from the light source, and a processor that controls a wavelength of the light emitted from the light source based upon an output value of the wavelength monitor circuit, wherein the wavelength monitor circuit has a wavelength filter that outputs four light components with optical phases shifted by 90 degrees from one another and multiple photo detectors that detects the four light components output from the wavelength filter, and wherein the processor selects at least one of the four light components, calculates a ratio of a monitor value of the selected light component to a total sum of monitor values of the four light components, and adjusts the wavelength of the light source so as to bring the ratio to be closer to a target ratio at a designated wavelength.

Claim (Index 5):
The wavelength tunable light source as claimed in  claim 1 ,\n wherein the processor receives a first photocurrent value representing a first light component of the four light components, a second photocurrent value representing a second light component of the four light components, and a third photocurrent value representing a combination of third and fourth light components.
