  ABSTRACT: A nanoplasmonic loop–stub structure is proposed. Its fundamental properties are studied and compared with those of single-stub and double-stub structures of similar structural parameters. The results show that loop–stub structure has two sets of resonances. One set is similar to the resonances of single-stub and double-stub structures; these resonances are tunable by varying the widths of vertical branches. In contrast, other sets of resonances, which are unique to this structure, can be independently controlled by varying the width of the horizontal branch. The advantage of the loop–stub design over conventional stubs is that it can support traveling-wave-like modes in addition of the standing-wave modes. This feature offers a potential to realize directional add/drop filters for either forward or backward dropping. Moreover, it can provide efficient coupling between waveguides of different widths.

  ABSTRACT: Diagnosis of malaria is important for its medication and treatment. An automatic compact diagnostic tool will be advantageous especially for healthcare personnel working in developing countries, which lack trained professionals and high-quality equipments. Digital holographic microscopy is one of the advanced techniques for quantitative evaluation of cells, providing cell thickness information directly. This information obtained by interferometric comparison can be used to identify as well as to compare cells. Here, we describe the use of digital holographic interferometric microscopy (DHIM) with numerical focusing for automatic identification of malaria-infected red blood cells (RBCs). Identification is done by comparing its shape profile with that of a healthy RBC. A correlation function was used to separate healthy and malaria-infected RBCs.

• Article: Waveguide grating radial polarizer for the photolithography of circularly symmetrical optical elements

  [show abstract] [hide abstract]
  ABSTRACT: A radially periodic slab waveguide grating of concentric circular lines composed of a corrugated quartz substrate and a ZnS waveguiding layer under the condition of normal incidence TE0 mode coupling at the 442-nm wavelength of a circularly polarized HeCd laser exposure beam causes a close to 100% reflection of the local TE polarization and a high transmission of the local TM polarization, thus transmitting a radially polarized beam. The functionality demonstration is first made with a grating written by e-beam; then, the same element is obtained by means of a phase-mask projection with radial spatial frequency doubling with the first element used as a radial polarizer.

  ABSTRACT: A periodic grating is defined at the photoresist-coated wall of a circular cylinder with an integer number of particularly long grooves parallel to the generic lines by the holistic exposure of a radial phase mask to a normally incident collimated laser beam. The single-shot projected element corresponds to the inner grating of a high-resolution miniature shaft encoder.

• Article: Phase-Sensitive Detection for Optical Sensing With Porous Silicon

  ABSTRACT: We report on a photonic sensor with an ultralow limit of detection (LoD) based on a phase interrogation readout scheme together with an anisotropic porous silicon (PSi) membrane. First, the fabrication of porous free-standing membranes from medium doped (100) surface oriented silicon, with pore diameters suitable for the infiltration of biomolecules, around 50 nm, is reported. Then, the phase interrogation scheme for characterizing the PSi membranes is presented whose results show that while volumetric sensitivity increases with the membrane thickness, the resolution in the birefringence measurements decrease dramatically due to depolarization effects. The best LoD was found to be equal to 6.25 amp;times;10-6 RIU, from the thinnest 10- #x03BC;m-thick membrane. Finally, the thermooptic coefficient of the 10 #x03BC;m membrane was measured in an aqueous environment and shown to be equal to 8 #x00D7;10-4 rad/ #x00B0;C.

  ABSTRACT: We report on the fabrication and characterization of planar waveguides in an Er-doped tungsten-tellurite glass by implantation of 3.5 MeV N+ ions. Implantations were carried out in a wide fluence range of 1 . 10(16) divided by 8 . 10(16) ions/cm(2). Waveguides were characterized by m-line spectroscopy and spectroscopic ellipsometry. Irradiation-induced refractive index modulation saturated around a fluence of 8 . 10(16) ions/cm(2). Waveguides operating at 1550 nm were obtained in that material using 3.5 MeV N+ ion implantation.
