Abstract

Apparatuses and systems for a die-integrated aspheric mirror are described herein. One apparatus includes an ion trap die including a number of ion locations and an aspheric mirror integrated with the ion trap die.

First claim

What is claimed:

1. A die-integrated aspheric mirror apparatus, comprising:
an ion trap die comprising a plurality of separate ion locations each configured to separately trap an ion in a potential well; and
an ellipsoidal aspheric mirror physically integrated via a substrate die with the ion trap die; and
wherein the plurality of separate ion locations is positioned within and substantially parallel to a major axis of the ellipsoidal aspheric mirror.

2. The apparatus of claim 1 , wherein the ion trap die comprises a longitudinal axis and wherein the ellipsoidal aspheric mirror is configured to be physically integrated with the ion trap die such that a principal axis of the ellipsoidal aspheric mirror is substantially aligned with and perpendicular to the longitudinal axis of the ion trap die.

3. The apparatus of claim 1 , wherein the ion trap die comprises a horizontal axis and wherein the ellipsoidal aspheric mirror is configured to be physically integrated with the ion trap die such that a principal axis of the ellipsoidal aspheric mirror is substantially aligned with the horizontal axis of the ion trap die.

4. The apparatus of claim 1 , wherein:
the major axis of the ellipsoidal aspheric mirror is substantially parallel to a longitudinal axis of the ion trap die; and
a minor axis of the ellipsoidal aspheric mirror is substantially perpendicular to a horizontal axis of the ion trap die.

5. The apparatus of claim 1 , wherein the ion trap die and the ellipsoidal aspheric mirror are both physically integrated with a substantially planar surface of the substrate die.

6. A die-integrated aspheric mirror system, comprising:
an ion trap die comprising a plurality of separate ion locations each configured to separately trap an ion in a potential well;
a first aspheric mirror having an ellipsoidal configuration physically integrated with the ion trap die;
a first light source configured to promote emission of fluorescent light by excitation of at least one ion trapped in the plurality of separate ion locations, wherein the first light source is positioned distal to the first aspheric mirror relative to the ion trap die; and
a first plurality of optical fibers positioned between the first aspheric mirror and the ion trap die, wherein the plurality of optical fibers is configured to collect fluorescent light reflected by the first aspheric mirror that was emitted from the plurality of separate ion locations.

7. The system of claim 6 , further comprising a number of apertures in the first aspheric mirror, wherein the first light source and the number of apertures in the first aspheric mirror are configured to aim light to promote emission of fluorescent light from a particular ion location of the plurality of separate ion locations.

8. The system of claim 7 , wherein the first aspheric mirror is configured to focus fluorescent light emitted from the particular ion location of the plurality of separate ion locations toward at least one designated optical fiber.

9. The system of claim 8 , further comprising a nub on the at least one designated optical fiber toward which the fluorescent light is focused,
wherein the nub is configured to collect the fluorescent light reflected at various angles by the first aspheric mirror by having a numerical aperture corresponding to the various angles to enable coupling with the reflected fluorescent light.

10. The system of claim 6 , wherein:
the first aspheric mirror is configured with a plurality of image locations between the first aspheric mirror and the ion trap die; and
the aspherical mirror is configured with a plurality of principal axes that correspond to the plurality of image locations.

11. The system of claim 6 , further comprising:
the ion trap die, the first aspheric mirror, and the first plurality of optical fibers all being physically integrated with a substantially planar surface of an underlying interposer die;
wherein a longitudinal axis and a horizontal axis of the ion trap die form a plane that is substantially parallel with the substantially planar surface of the underlying interposer die;
wherein longitudinal axes of the first plurality of optical fibers are perpendicular to the substantially planar surface of the underlying interposer die;
wherein the first aspheric mirror is embedded into the substantially planar surface of the underlying interposer die along an axis substantially perpendicular to a principal axis of the first aspheric mirror; and
wherein the ion trap die, the first aspheric mirror, a number of apertures in the first aspheric mirror, the first plurality of optical fibers, and a substantially planar surface of an underlying interposer die are configured to enable unobstructed optical access to the plurality of separate ion locations by light from the first light source.

12. The system of claim 6 , further comprising:
a second aspheric mirror having an ellipsoidal configuration physically integrated with the ion trap die, wherein the second aspheric mirror is on an opposite side of the ion trap die relative to the first aspheric mirror;
a second light source configured to promote emission of fluorescent light by excitation of at least one ion trapped in the plurality of separate ion locations; and
a second plurality of optical fibers positioned between the second aspheric mirror and the ion trap die, wherein the second plurality of optical fibers is configured to collect fluorescent light reflected by the second aspheric mirror that was emitted from the plurality of separate ion locations.

13. The system of claim 12 , wherein:
the first aspheric mirror and the second aspheric mirror each have a major axis positioned substantially parallel to a longitudinal axis of the ion trap die, wherein the first aspheric mirror and second aspheric mirror have opposing reflective surfaces; and
the first aspheric mirror has a first circumference and the second aspheric mirror has a second circumference, wherein the first circumference has at least an arc thereof that is separated by a distance from an opposing arc of the second circumference.

14. The system of claim 13 , wherein the distance by which the first circumference and the second circumference are separated enables unobstructed optical access to the ion trap die by at least one of a charge-coupled device camera and a third light source.

15. A die-integrated aspheric mirror system, comprising:
an ion trap die comprising a plurality of separate ion locations each configured to separately trap an ion in a potential well;
a first ellipsoidal aspheric mirror physically integrated with the ion trap die, wherein the plurality of separate ion locations is positioned within and substantially parallel to a major axis of the first ellipsoidal aspheric mirror;
