A liquid crystal cell structure is provided. The liquid crystal cell structure includes: two polarizers; and a liquid crystal diffractive light modulating cell placed between the two polarizers. The cell includes: two transparent substrates treated by photoalignment; and a ferroelectric liquid crystal layer disposed between the two transparent substrates with current conducting layers, the ferroelectric liquid crystal layer comprising ferroelectric liquid crystals. The two transparent substrates treated by photoalignment are configured to provide multiple alignment domains in the ferroelectric liquid crystals with a planar surface orientation. Adjacent domains of the multiple alignment domains are oriented at an angle with respect to each other.

Technologies are generally described for techniques useful in an interferometer system. In some examples, a system may include a first waveguide effective to propagate a first wave in a first mode. In some examples, the system may include a second waveguide effective to, in response to the first wave, propagate second and third waves in second and third modes, respectively. In some examples, the second waveguide may be effective to reflect the second and third waves off a reflection surface to produce first, second, third and fourth reflected waves. In some examples, the second waveguide may be effective to propagate the first and third reflected waves in the second mode and propagate the second and fourth reflected waves in the third mode.

A novel method suitable for commercially mass production of hollow microneedle with high quality for delivery of drugs across or into biological tissue is provided. It typically includes the following processes: (1) coating an elongated template of a first material with a second material to form a cover; (2) removing tips of the template and cover to form an opening in the cover; and (3) removing the template of the first material to obtain hollow microneedles of the second material. This simple, efficient and cost-effective fabrication method can mass produce hollow microneedle arrays involving no complicated and expensive equipments or techniques, which can be used in commercial fabrication of hollow needles for delivering drugs or genes across or into skin or other tissue barriers with advantages of minimal damage, painless, long-term and continuous usages.
