Abstract
Abstract A process and device for connecting an optical fibre and an integrated optical component comprising a wave guide. The fibre and the component each have an end adapted for connection. The component is attached to a main support. The fibre is attached to a fibre support so that the end of the fibre extends beyond such fibre support. The end of the fibre is attached to the end of the component so as to allow light to pass from the fibre to the component and conversely. Then the fibre support and the main support are rigidly connected to each other.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A process for connecting at least one optical fibre and an integrated optical component comprising at least one wave guide, the optical fibre and the wave guide each having an end adapted for connection, wherein it comprises in: attaching the component to a main support, attaching in a non-detachable way the fibre to a fibre support so that the end of the fibre extends beyond such fibre support, attaching the end of the fibre to the end of the wave guide so as to enable light to pass from the fibre to the wave guide and conversely, and then rigidly connecting to one another the fibre support and the main support.
Claim 2
Dependent Claim
111 words
A process for connecting at least one optical fibre and an integrated optical component comprising at least one wave guide, the optical fibre and the wave guide each having an end adapted for connection, wherein it comprises in: attaching the component to a main support, attaching in a non-detachable way the fibre to a fibre support so that the end of the fibre extends beyond such fibre support, attaching the end of the fibre to the end of the wave guide so as to enable light to pass from the fibre to the wave guide and conversely, and then rigidly connecting to one another the fibre support and the main support.
Claim 3
Dependent Claim
33 words
A process according to claim 1, wherein the end of the optical fibre is attached to the end of the wave guide by means of a glue which is transparent to said light.
Claim 4
Dependent Claim
14 words
A process according to claim 2, wherein the glue is also a polymerizable glue.
Claim 5
Dependent Claim
79 words
A process according to claim 2, wherein the glue intended for attaching the end of the fibre to the end of the wave guide is also a glue which can be polymerized by means of a radiation and is polymerized by aiming the radiation at the glue via a sighting telescope focussed on such ends, the ends being brought together and connected by the glue, while the telescope enables the relative positioning of the ends to be controlled beforehand.
Claim 6
Dependent Claim
63 words
A process according to claim 3, wherein the fibre support is rigidly connected to the main support by a polymerizable glue, and the glue intended for attaching the end of the fibre to the end of the wave guide is polymerized before the glue adapted to connect the fibre support rigidly to the main support, while avoiding any polymerization of the last-mentioned glue.
Claim 7
Dependent Claim
115 words
A process according to claim 5, wherein the glue intended for connecting the fibre support and the main support rigidly to one another is a glue which can be polymerized by a radiation, the fibre support comprising a member adapted to at least partially transmit the radiation provided to polymerize the glue intended for connecting the fibre support and the main support rigidly to one another, and the last-mentioned glue is so disposed between such member for partially transmitting the radiation and the main support as to connect these last-mentioned members rigidly to one another, the last-mentioned glue being polymerized by transmitting to it the corresponding radiation via the member adapted to transmit the radiation.
Claim 8
Dependent Claim
48 words
A process according to claim 1, wherein before being attached to one another the end of the fibre and the end of the wave guide are so positioned in relation to one another that a maximum of light passes from the fibre to the wave guide or conversely.
Claim 9
Independent Claim
111 words
A device for connecting at least one optical fibre and an integrated optical component comprising at least one wave guide, the optical fibre and the wave guide each having an end intended for connection, wherein the device comprises a main support to which the component is attached, and a fibre support to which the fibre is attached, so that the end of the latter extends beyond the fibre support, and the fibre support is rigidly connected to the main support, the end of the fibre being previously attached to the end of the wave guide so as to enable light to pass from the fibre to the wave guide and conversely.
Claim 10
Independent Claim
111 words
A device for connecting at least one optical fibre and an integrated optical component comprising at least one wave guide, the optical fibre and the wave guide each having an end intended for connection, wherein the device comprises a main support to which the component is attached, and a fibre support to which the fibre is attached, so that the end of the latter extends beyond the fibre support, and the fibre support is rigidly connected to the main support, the end of the fibre being previously attached to the end of the wave guide so as to enable light to pass from the fibre to the wave guide and conversely.
Claim 11
Dependent Claim
28 words
A device according to claim 8 wherein the end of the optical fibre is attached to the end of the wave guide by means of a light-transparent glue.
Claim 12
Dependent Claim
95 words
A device according to claim 8 wherein the fibre support is rigidly connected to the main support by means of a glue which can be polymerized by a radiation, the fibre support comprises a member adapted to at least partially transmit the radiation provided to polymerize the glue intended for connecting the fibre support and the main support rigidly to one another, and the last-mentioned glue is disposed between such member adapted to transmit radiation and the main support, the last-mentioned glue being polymerized by transmitting to it the corresponding radiation via the radiation-transmitting member.
Claim 13
Dependent Claim
65 words
A process according to claim 4, wherein the fibre support is rigidly connected to the main support by a polymerizable glue, and the glue adapted to attach the end of the fibre to the end of the wave guide is polymerized before the glue is adapted to connect the fibre support rigidly to the main support, while avoiding any polymerization of the last mentioned glue.
Claim 14
Dependent Claim
115 words
A process according to claim 11, wherein the glue intended for connecting the fibre support and the main support rigidly to one another is a glue which can be polymerized by a radiation, the fibre support comprising a member adapted to at least partially transmit the radiation provided to polymerize the glue intended for connecting the fibre support and the main support rigidly to one another, and the last-mentioned glue is so disposed between such member for partially transmitting the radiation and the main support as to connect these last-mentioned members rigidly to one another, the last-mentioned glue being polymerized by transmitting to it the corresponding radiation via the member adapted to transmit the radiation.
