Abstract: Alignment of a laser apparatus is achieved by actively aligning components of the laser apparatus and then passively deriving an optical axis from that alignment. This passive derivation can be achieved by identifying features of an actively aligned optical element, deriving positional data for those features, and developing an optical axis from that positional data. The derivation of positional data may be performed over a particular coordinate system of an image taken of the feature, e.g., obtained by a vision system. The positional data and optical axis may be extrapolated out to a reference coordinate system for use in passively aligning other optical elements.

Abstract: Semi-integrated external cavity diode laser (ECDL) (300A) designs including integrated structures (302A) comprising a gain section (400), phase control section (402), and optional modulator section (404). Each integrated structure includes a waveguide (406) that passes through each of the sections. A mirror (408) is defined in the structure to define one end of a laser cavity. A reflective element (314) is disposed generally opposite a rear facet (410) of the gain section (400), forming an external cavity therebetween. A tunable filter (310) is disposed in the external cavity to effectuate tuning of the laser. During operation, a modulated drive signal (332) is provided to the phase control section (402). This modulates an optical path length of the laser cavity, which produces an intensity (amplitude) modulation in the laser output. A detector is employed to produce a feedback signal indicative of the intensity modulation that is used for tuning the laser in accordance with a wavelength locking servo loop. Upon passing through the modulator section (404), an optical signal is modulated with data (722).
