A novel tunable liquid crystal microaxicon array is proposed and experimentally demonstrated. The proposed structure is capable of generating tunable axicons [thousands of elements) of micrometric size, with simple control [four control voltages) and low voltage, and is totally reconfigurable. Depending on the applied voltages, control over the diameter, as well as the effective wedge angle, can be achieved. Controls over the diameter ranging from 107 to 77 \aa have been demonstrated. In addition, a control over the phase profile tunability, from 12» to 24» radians, has been demonstrated. This result modifies the effective cone angle. The diameter tunability, as well the effective cone angle, results in a control over the nondiffractive Bessel beam distance. The RMS wavefront deviation from the ideal axicon is only A/3. The proposed device has several advantages over the existing microaxicon arrays, including being simple having a low cost. The device could contribute to developing new applications and to reducing the fabrication costs of current devices. limitations on the axicon profile height and thus the axicon angle. To overcome these drawbacks, another technique based on using a multistep micromolding process [21] has been recently proposed. In general, the proposed ideas use complex fabricating processes. Moreover, a reconfiguration of the final device is not possible.The parameters defining an axicon are the aperture diameter (d) and the wedge angle (j). In order to increase the nondiffractive distance of a Bessel beam (« max ), one of these parameters has to be modified (_z msK ~ d/y). Until now, these parameters were modified in the fabrication process. As commented above, the fabrication processes proposed until now produce limitations in the microaxicon parameters. One solution is the use of liquid-crystal-on-silicon spatial light modulators (LCoSSLMs) [22]. Despite this, the main problem is the low phase shift achieved by this device (usually 2n) and the price. Another drawback could be the characteristic structure, based on pixels surrounded by opaque areas, causing losses of light efficiency and possible aliasing in the case of micro-optical systems. To solve this problem some manufacturers use a special anti-reflection coating to ensure that the influence of the pixellated structure is minimized and thus the diffraction losses. In addition, LCoS-SLMs have residual phase distortions and a limited resolution [22]. Another option has been reported [23], In this work a tunable MEMS axicon mirror array is proposed. It shows a high tunability by controlling the wedge angle with temperature changes. The required temperature control could complicate the final device.In this Letter, a microaxicon array with high tunability and simple control is proposed. A control over the aperture and effective wedge angle is experimentally demonstrated. This device is simple and reconfigurable with low voltage signals.
