    2. Highly-efficient, octave spanning soliton self-frequency shift using a specialized photonic crystal fiber with low OH loss

      Highly-efficient, octave spanning soliton self-frequency shift using a specialized photonic crystal fiber with low OH loss
      We report the first demonstration of efficient, octave spanning soliton self-frequency shift. In order to achieve this we used a photonic crystal fiber with reduced OH absorption and widely spaced zero-dispersion wavelengths. To our knowledge, this is the largest reported frequency span for a tunable, fiber-based source. In addition, we observe the generation of light above 2 μm directly from a Ti:Sapphire laser in the form of Cerenkov emission ...

    3. Chromatic dispersion compensation of an OCT system with a programmable spectral filter

      Chromatic dispersion compensation of an OCT system with a programmable spectral filter
      We demonstrate the use of a programmable optical spectral filter to compensate all orders of chromatic dispersion in an all-fibre Fourier-domain optical coherence tomography system at 1550 nm. The pointspread- function, originally 58 μm wide, asymmetric, with strong sidelobes, is successfully made symmetric and recompressed to 37 μm, close to the theoretical limit of 36 μm.

    4. Impact of Ethnicity on the Correlation of Retinal Parameters with Axial Length

      Impact of Ethnicity on the Correlation of Retinal Parameters with Axial Length
      Purpose. To examine whether the relationship of axial length (AL) to retinal nerve fiber layer (RNFL) and macular parameters measured by optical coherence tomography (OCT) differs according to ethnicity. Methods. As part of the Sydney Myopia Study, 2353 children from grade 7 (age range, 11.1–14.4 years) completed detailed ocular examinations in the 2004–2005 school year. AL was measured with noncontact interferometry and Stratus OCT was performed ...

    5. Normal Macular Thickness Measurements Using Optical Coherence Tomography in Healthy Eyes of Adult Chinese Persons: The Handan Eye Study

      Normal Macular Thickness Measurements Using Optical Coherence Tomography in Healthy Eyes of Adult Chinese Persons: The Handan Eye Study
      Purpose: To describe macular thickness measured by optical coherence tomography (OCT) in healthy eyes of adult Chinese persons.Design: Population-based cross-sectional study.Participants: Chinese adults aged 30+ years who were residents of Handan, North China.Methods: The Handan Eye Study is a population-based study of eye disease in Chinese persons. Eligible residents underwent a comprehensive ophthalmic examination including OCT (Stratus OCT, Carl Zeiss Meditec Inc., Jena, Germany). Fast macular thickness ...
