TL;DR: In this paper, a spiral phaseplate can convert a TEM00 laser beam into a helical wavefront beam with a phase singularity at its axis, and the diffractive-optical effect of the spiral phase plate is implemented by index matching a macroscopic structure in an optical immersion.

TL;DR: In this paper, a cantilever device is designed to have a flat structure with a proof mass added to the end to create electrical energy via the piezoelectric effect.
Abstract: A thin film lead zirconate titanate, Pb(Zr,Ti)O 3 (PZT), MEMS power generating device is developed. It is designed to resonate at specific frequencies from an external vibrational energy source, thereby creating electrical energy via the piezoelectric effect. Our cantilever device is designed to have a flat structure with a proof mass added to the end. The Pt/Ti top electrode is patterned into an interdigitated shape on top of the sol–gel-spin coated PZT thin film in order to employ the d33 mode of the piezoelectric transducer. This d33 mode design generates 20 times higher voltage than that of the d31 mode design of the same beam dimension. The base-shaking experiments at the first resonant frequency (13.9 kHz) generate charge proportional to the tip displacement of the cantilever with a linearity coefficient of 4.14 pC/ m. A

TL;DR: In this article, a new type of optical waveguide utilizing an antiresonant reflector was described, which gave losses as low as 0.4 dB/cm for the TE mode.
Abstract: A new type of optical waveguide utilizing an antiresonant reflector is described. Implementation in the SiO2‐Si system gave losses as low as 0.4 dB/cm for the TE mode. The TM mode loss is >60 dB/cm, making the device an excellent planar technology integrated optic polarizer.
