Abstract
The disclosure relates to the field of optical components in which a fiber is aligned on a laser, LED or similar device. The fiber is fixed into a sleeve clamped by a "keyhole" shaped clamp. The optical component is fixedly joined to a base in which a slot is parallel to the optical axis of the component. The clips of the clamp are introduced into the slot which is designed to give three degrees of liberty. When the alignment is obtained in dynamic operation, the parts are fixed by solders made by laser. The device can be applied to optical heads.
Claims5
An alignment and fastening device for connecting an optical fiber to an optoelectronic component, said optical fiber having an optical axis, comprising:
- a base member to which said optoelectronic component is fixed, said base member having a slot formed therein in a direction parallel to said optical axis;
- a metal sleeve through which said optical fiber is passed;
- and
- a metal clamp in the shape of a hairpin or keyhole,
- wherein said metal clamp is movable within said slot in x, y and z directions, said x direction being a rotational arc direction having an axis of rotation parallel to the optical axis of said optical fiber, said y direction being a linear direction perpendicular to the optical axis of said optical fiber, and said z direction being a direction in which the optical axis of said optical fiber extends.
