Abstract

Apparatus comprising at least one optical device ( 106 ) optically coupled to at least one waveguide ( 111 ) on an optical chip ( 100 ), characterized in that: (i) the optical device ( 106 ) is optically aligned with the waveguide ( 111 ) by aligning means ( 114, 116 ); (ii) the aligning means ( 114, 116 ) comprises at least one male member ( 114 ) and at least one female ( 116 ) member which locate together; (iii) one of the male member ( 114 ) and the female member ( 116 ) is positioned on the optical chip ( 100 ); (iv) the other one of the male member ( 114 ) and the female member ( 116 ) is positioned on a capping chip ( 102 ); and (v) the apparatus includes a mirror ( 108 ) for reflecting light from the optical device ( 106 ) to the waveguide ( 111 ).

Claims (15)

1. Apparatus comprising at least one optical device optically coupled to at least one waveguide on an optical chip, characterised in that:

(i) the optical device is optically aligned with the waveguide by aligning means;

(ii) the aligning means comprises at least one male member and at least one female member which locate together;

(iii) one of the male member and the female member is positioned on the optical chip;

(iv) the other one of the male member and the female member is positioned on a capping chip; and

(v) the apparatus includes a mirror for reflecting light from the optical device to the waveguide.

2. Apparatus according to claim 1 in which the female member is positioned on the optical chip, and in which the male member is positioned on the capping chip.

3. Apparatus according to claim 1 in which the optical device is located in a groove in the capping chip.

4. Apparatus according to claim 3 in which the groove is a V-shaped groove.

5. Apparatus according to claim 1 in which the optical device is an optical fibre.

6. Apparatus according to claim 1 in which the optical device is a laser.

7. Apparatus according to claim 1 in which the male member is made of silicon nitride.

8. Apparatus according to claim 1 in which the optical device is coupled to the waveguide in the plane of the waveguide.

9. Apparatus according to claim 1 in which the optical device is coupled to the waveguide out of the plane of the waveguide.

10. Apparatus according to claim 9 and including a grating for coupling the optical device to the waveguide.
