Abstract: Embodiments herein describe optical devices that include focusing elements in or on a substrate on which a laser source is disposed. That is, the focusing element can be arranged on a same surface of the substrate as the laser source. In one embodiment, the laser source emits an optical signal that is parallel with the same surface of the substrate. A turning mirror can be used to direct the optical signal in a direction perpendicular to the surface so that the optical signal is incident on the focusing element.

Abstract: Embodiments here describe a Faraday rotator ball lens that can be used in an optical device to focus received light and prevent back reflections from reaching a light source. In one embodiment, the isolator ball lens includes an optic axis that should be aligned with the direction of the received light in order to rotate the light so that back reflections cannot reach the light source. To do so, the isolator ball lens is placed on a holder which is then vibrated, shaken, or an aerodynamic levitation is applied in the presence of a magnetic field. The magnetic field is aligned with a desired direction of the optic axis of the isolator ball lens as the ball lens. As a result, when the ball lens is moved, the magnetic field rotates the ball lens and aligns its optic axis in the desired direction.
