Abstract

An optically powered optical modulator comprises an optical modulation component, such as an electro-optical modulator, acousto-optic modulator or magneto-optic modulator, in combination with one or two lens assemblies positioned at one or both apertures of the optical modulation component, so that the optical modulator formed by the combination of the lens assembly or assemblies and the optical modulation component has optical focus power.

Claims (15)

1. An optically powered optical modulator, comprising:

an optical modulation component having an optical axis and first and second opposed optically clear component apertures defined by the optical axis and operable to modulate light aligned with the optical axis;

an optically powered first lens assembly secured at the first component aperture;

the first lens assembly having an optically clear first lens aperture in optical alignment with the first component aperture; and

a housing carrying the optical modulation component and the first lens assembly.

2. The optical modulator of claim 1 , wherein the optical modulation component is selected from the group consisting of electro-optical component, acousto-optical component and magneto-optical component.

3. The optical modulator of claim 1 , wherein the first lens assembly comprises a single lens.

4. The optical modulator of claim 1 , wherein the first lens assembly comprises a plurality of individual lenses secured in optical alignment with one another.

5. The optical modulator of claim 1 , further comprising:

an optically powered second lens assembly secured at the second cell aperture;

the second lens assembly having an optically clear second lens aperture in optical alignment with the second component aperture and with the first lens aperture;

wherein the housing carries the second lens assembly.

6. The optical modulator of claim 5 , wherein the first lens assembly and the second lens assembly each comprise a single lens.

7. The optical modulator of claim 5 , wherein the first lens assembly and the second lens assembly each comprise a plurality of individual lenses secured in optical alignment with one another.

8. The optical modulator of claim 5 , wherein the first lens assembly comprises a single lens and the second lens assembly comprises a plurality of individual lenses secured in optical alignment with one another.
