Wavelength lockers, which monitor the wavelength drift of a laser's beam due to aging, are tunable to adjust for manufacturing misalignments between its various optical components. Tuning is accomplished by adjusting the position of a collimating lens using a flexure. Adjusting the lens position changes the angle of incidence of a monitored beam relative to a fixed filter and detector and avoids the challenging manufacturing task of rotating the filter and detector to achieve the same result.

Back facet wavelength locker tuning and assembly method

A wavelength locker for monitoring the wavelength drift of a laser uses a pair of detectors for detecting a power component of the laser beam and a wavelength component of the laser beam, respectively. Various positionings of the power detector and/or variations to the collimating lens provide a compact arrangement with fewer components.
