The invention relates to a light modulator including a substrate having a surface and a modulation assembly coupled to the substrate that includes a modulation element and a first compliant beam. The first compliant beam includes a first segment that extend away from a first anchor and a second segment that extends back towards the first anchor. The length of the first segment is different than the length of the second segment.
1. A light modulator comprising: a substrate; anda modulation assembly coupled to the substrate, the modulation assembly including a modulation element and a first compliant beam, the first compliant beam including a first segment that extends away from a first anchor and a second segment that exten
1. A light modulator comprising: a substrate; anda modulation assembly coupled to the substrate, the modulation assembly including a modulation element and a first compliant beam, the first compliant beam including a first segment that extends away from a first anchor and a second segment that extends back towards the first anchor, wherein:the length of the first segment is different than the length of the second segment, andthe first compliant beam includes an electrode configured to actuate movement of the modulation element. 2. The light modulator of claim 1, wherein one of the first segment and second segment includes at least one elongating portion that increases the length of the respective one of the first segment and the second segment. 3. The light modulator of claim 2, wherein the at least one elongating portion has a shape in the form of at least one of a loop shape, an s-curve shape, a zig-zag shape, and a meandering shape. 4. The light modulator of claim 2, wherein the at least one elongating portion includes one or more corners. 5. The light modulator of claim 2, wherein the at least one elongating portion includes one or more bends. 6. The light modulator of claim 1, wherein the difference in length between the first segment and the second segment is configured to bend the compliant beam in a desired direction. 7. The light modulator of claim 6, further comprising a second compliant beam offset from the first compliant beam, wherein the distance between the first compliant beam and the second compliant beam is determined at least in part by the difference in the length of the first segment with respect to the length of the second segment. 8. The light modulator of claim 7, wherein the distance between the first compliant beam and the second compliant beam is determined by including at least one elongating portion along one of the first segment and the second segment. 9. The light modulator of claim 8, wherein the distance between the first compliant beam and the second compliant beam is established after release from a mold. 10. The light modulator of claim 7, wherein the second compliant beam includes an electrode, the second compliant beam providing support for the modulation element and cooperatively interacting with the first compliant beam for actuating movement of the modulation element. 11. The light modulator of claim 1, wherein at least one of the first segment and the second segment is at least partially curved to promote bending in a desired direction. 12. The light modulator of claim 11, wherein the first compliant beam is pre-configured in a mold such that at least one of the first segment and second segment is at least partially curved upon release from the mold. 13. The light modulator of claim 1, wherein the first segment and the second segment extend in a substantially parallel direction with respect to each other. 14. An electromechanical device comprising: a substrate; andan electromechanical assembly coupled to the substrate, the electromechanical assembly including a movable element and a first compliant beam, the first compliant beam including a first segment that extends away from a first anchor and a second segment that extends back towards the first anchor, wherein: the length of the first segment is different than the length of the second segment, andthe first compliant beam includes an electrode configured to actuate movement of the movable element. 15. The electromechanical device of claim 14, wherein one of the first segment and second segment includes at least one elongating portion that increases the length of the respective one of the first segment and the second segment. 16. The electromechanical device of claim 15, wherein the at least one elongating portion has a shape in the form of at least one of a loop shape, an s-curve shape, a zig-zag shape, and a meandering shape. 17. The electromechanical device of claim 15, wherein the at least one elongating portion includes one or more corners. 18. The electromechanical device of claim 15, wherein the at least one elongating portion includes one or more bends. 19. The electromechanical device of claim 14, wherein the difference in length between the first segment and the second segment is configured to bend the compliant beam in a desired direction.
