Abstract: 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.

Abstract: Optoelectronic modules and methods of manufacturing the same are disclosed. Some of the disclosed modules employ a tape automated bonding substrate (TAB) which is surface mounted with circuit elements. In some examples, the TAB is mounted to a rigid substrate after a fiber submount is passively positioned on the substrate. This modular manufacturing technique limits the value of yield loss. In some example modules, only one active alignment is employed to manufacture the module. Some of the disclosed modules include an optically pluggable connector.

Abstract: 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.

Abstract: Modern optoelectronic components have very tight coupling tolerances. Small misalignments of a strong lens that occur during the alignment and bonding process seriously degrade optical coupling. A weak lens is actively mounted using a flexure to correct misalignments of the strong lens. Since the weak lens does not exert as much steering force on a beam for a similar movement as the strong lens, misalignments that may occur during weak lens positioning and bonding do not appreciably degrade coupling.
