Abstract
Embodiments are directed to laser emitter modules and methods and devices for making the modules. Some module embodiments are configured to provide hermetically sealed enclosures that are convenient and cost effective to assemble and provide for active alignment of optical elements of the module.
Claims21
A ferrule assembly for positioning an input surface of an optical fiber, comprising:
- an outer sleeve including a barrel portion with an inner bore extending along an axial length of the barrel portion and a flange member extending radially from the barrel portion, the flange member including a distal facing front surface;
- a fiber attachment sleeve which is secured to the outer sleeve and which includes an outer surface sized to slide axially within the inner bore of the outer sleeve, an axial fiber receiving lumen disposed concentrically with the outer surface and an input end;
- and
- an optical fiber secured to the fiber attachment sleeve with an input end of the optical fiber being disposed distally beyond the input end of the fiber attachment sleeve and disposed within the inner bore of the outer sleeve.

- an outer sleeve including a barrel portion with an inner bore extending along an axial length of the barrel portion and a flange member extending radially from the barrel portion, the flange member including a distal facing front surface;
- a fiber attachment sleeve which is secured to the outer sleeve and which includes an outer surface sized to slide axially within the inner bore of the outer sleeve, the fiber attachment sleeve including a stepped axial lumen which is concentric with an outer surface of the fiber attachment sleeve and which includes a minor transverse dimension portion of the stepped axial lumen which extends extending proximally from an input end of the fiber attachment sleeve and a major transverse dimension portion of the stepped axial lumen disposed proximally of the minor transverse dimension portion, the minor transverse dimension portion having a transverse dimension which is stepped down relative to a transverse dimension of the major transverse dimension portion;
- and
- an optical fiber which is secured within the stepped axial lumen of the fiber attachment sleeve with an input end of the optical fiber being disposed distally beyond the input end of the fiber attachment sleeve and being disposed within the inner bore of the outer sleeve.
