## Abstract

An optoelectronic assembly connectorizing light through an optical fiber. A housing includes an axially extending cavity. A transparent window is located at a first end of the cavity. A termination part is located at a second end of the cavity. The cavity forms a cooling chamber being fed by a flowing coolant surrounding an envelope surface of the optical fiber. The optical fiber is in optical contact with the window and extends out of the assembly through the termination part. The optical fiber is fixed in the termination part with a guiding glue.

## Claims

### Claim 1

An optoelectronic assembly for connectorizing an optical fiber, the assembly comprising:
a housing with an axially extending cavity, the cavity comprising a first end where light is transmitted into the assembly and a second end where light is transmitted out of the assembly;
a termination part located at the second end of the cavity, wherein the cavity forms a cooling chamber being fed by a flowing coolant surrounding an envelope surface of said optical fiber, wherein the optical fiber extends out of the assembly through the termination part, and
a guiding glue configured to fix the optical fiber in the termination part, wherein the guiding glue has a lower refractive index than the envelope surface of the optical fiber in contact with the guiding glue.

### Claim 2 (depends on 1)

The assembly according to claim 1, wherein the guiding glue is optically transparent or semi-transparent for wavelengths of transmitted light.

### Claim 3 (depends on 1)

The assembly according to claim 1, wherein the guiding glue forms a coolant seal in the termination part.

### Claim 4 (depends on 1)

The assembly according to claim 1, wherein the guiding glue is arranged to fix the optical fiber in the termination part out of contact with the termination part.

### Claim 5 (depends on 1)

The assembly according to claim 1, wherein the optical fiber comprises a core, at least one cladding layer and at least one jacket layer, wherein the jacket layer is terminated within the guiding glue.

### Claim 6 (depends on 5)

The assembly according to claim 5, wherein the optical fiber comprises at least one buffer layer in contact with the jacket layer.

### Claim 7 (depends on 6)

The assembly according to claim 6, wherein the buffer layer is terminated within the guiding glue.

### Claim 8 (depends on 7)

The assembly according to claim 7, wherein the buffer layer is terminated a predetermined distance inside the cavity.

### Claim 9 (depends on 1)

The assembly according to claim 1, wherein the guiding glue comprises at least one of silicone, acrylic high-polymer, acrylate resin, and epoxy resin.

### Claim 10 (depends on 1)

The assembly according to claim 1, wherein the guiding glue is at least partially located in a hollow portion of the assembly extending from the termination part into the cavity.

### Claim 11 (depends on 10)

The assembly according to claim 10, wherein the hollow portion is an integral part of the termination part.

### Claim 12 (depends on 10)

The assembly according to claim 10, wherein the hollow portion comprises a cylindrical reflector extending from the termination part into the cavity.

### Claim 13 (depends on 10)

The assembly according to claim 10, wherein the hollow portion comprises a light reflecting and heat conducting material.

### Claim 14 (depends on 1)

The assembly according to claim 1, further comprising:
a sealing extending between the optical fiber and the termination part, wherein the sealing is located between the guiding glue and the cooling chamber.

### Claim 15 (depends on 10)

The assembly according to claim 10, wherein at least the hollow portion comprises a transparent material.

### Claim 16 (depends on 1)

The assembly according to claim 1, wherein a portion of the cladding layer extending through the cavity between the window and the termination part comprises a mode stripper.

### Claim 17 (depends on 1)

The assembly according to claim 1, further comprising:
a transparent window located at the first end of the cavity, wherein the optical fiber is in optical contact with the window.

### Claim 18 (depends on 13)

The assembly according to claim 13, wherein the light reflecting and heat conducting material comprises at gold, copper or a copper alloy.

### Claim 19 (depends on 15)
