Abstract
Abstract A device for coupling a light source, in particular a semiconductor laser, to an optical fiber in which the light source and the optical fiber are each connected to a cylindrical or part-cylindrical support and a coupling member is provided having two V-shaped grooves enclosing mutually a substantially right angle, in which the cylindrical supports, possibly carried by an additional member, after their mutual adjustment in the V-shaped grooves, are secured to the contact member. One of the supports may advantageously be provided in a V-shaped groove of a cylindrical or part-cylindrical auxiliary member which is secured in one of the V-shaped grooves of the coupling member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
39 words
A device for coupling a light source to an optical fiber, comprising cylindrically-shaped supports for the light source and optical fiber respectively, a coupling-member having two substantially orthogonal V-shaped grooves the cylindrical supports being secured in the V-shaped grooves.
Claim 2
Independent Claim
39 words
A device for coupling a light source to an optical fiber, comprising cylindrically-shaped supports for the light source and optical fiber respectively, a coupling-member having two substantially orthogonal V-shaped grooves the cylindrical supports being secured in the V-shaped grooves.
Claim 3
Dependent Claim
38 words
A device as claimed in claim 1, wherein one of the supports is provided in a V-shaped groove of an auxiliary cylindrically-shaped member, said auxiliary member being secured in one of the V-shaped grooves of the coupling member.
Claim 4
Dependent Claim
71 words
A device as claimed in claim 2, wherein the coupling member comprises two V-shaped grooves located in one plane, the cylindrically-shaped auxiliary member comprising a V-shaped groove in one of its end faces in which the support of the light source is secured, the said support comprising a connection surface for the light source such that the light source lies on the center line of the cylindrical surface of the support.
Claim 5
Dependent Claim
46 words
A device as claimed in claim 2, wherein the V-shaped grooves of the coupling member cross each other and the auxiliary member is a sector of a circular cylinder, the V-shaped groove in the auxiliary member being at right angles to the axis of said cylinder.
Claim 6
Dependent Claim
31 words
A device as claimed in claim 2 wherein at least one of the cylindrical supports and the auxiliary member are surrounded adjacent their end faces by a projecting circular adjustment ring.
Claim 7
Dependent Claim
18 words
A device as claimed in claim 2 wherein the supports are secured in the grooves with an adhesive.
