Abstract
A wavelength locker may include a first optical detector configured to detect light, wherein the first optical detector is at least partially transparent to the light. The wavelength locker may further include an optical interferometer optically coupled to the first optical detector and to a second optical detector. The optical interferometer is configured to selectively filter the light that passes through the first optical detector and the second optical detector detects the filtered light. An optical module or package may include the wavelength locker coupled to a laser for locking an emission wavelength of the laser.
