    2. A comparative study of noise in supercontinuum light sources for ultra-high resolution optical coherence tomography at 1300 nm

      A comparative study of noise in supercontinuum light sources for ultra-high resolution optical coherence tomography at 1300 nm
      Supercontinuum (SC) light is a well-established technology, which finds applications in several domains ranging from chemistry to material science and imaging systems [1-2]. More specifically, its ultra-wide optical bandwidth and high average power make it an ideal tool for Optical Coherence Tomography (OCT). Over the last 5 years, numerous examples have demonstrated its high potential [3-4] in this context. However, SC light sources present pulse-to-pulse intensity variation that can limit ...

    3. 2nd Canterbury Conference on Optical Coherence Tomography (emphasis on broadband optical sources) September 2017

      2nd Canterbury Conference on Optical Coherence Tomography (emphasis on broadband optical sources) September 2017
      This 3 day conference will be dedicated to recent advances in measurement and imaging conditioned by progress in enlarging the spectrum of the optical source. The larger the bandwidth of the broadband optical source used in spectrometer based OCT, and of the tuning bandwidth of swept lasers used in swept source OCT, the better the axial resolution. However, an increase in the source bandwidth brings with it other problems that ...

    4. Wavelength tunable photon source with sealed inner volume

      Wavelength tunable photon source with sealed inner volume
      There is presented a method of providing a wavelength tunable photon source (200), comprising bonding a first element (101) with a first mirror (106), a second element (102) with a second mirror (108) and a third element (103) with a photon emitter together in a structure enclosing an inner volume (214) being a sealed volume, and forming a bonding interface (212) which is gas-tight, so that the first mirror (106 ...

    5. 15 Open PhD Positions within Supercontinuum Light Sources and Applications at Technical University of Denmark

      15 Open PhD Positions within Supercontinuum Light Sources and Applications at Technical University of Denmark
      We are seeking 15 skilled candidates for PhD positions across Europe in supercontinuum light sources and applications. The candidates should have a background in physics and interest in nonlinear optics, fibre optics and waveguides, and laser physics. SUPUVIR ( SUPercontinuum broadband light sources covering UV to IR applications ) is a new Innovative Training Network (ITN) funded by the European H2020 programme. SUPUVIR will focus on so-called supercontinuum laser sources, which essentially ...

    6. Wavelength sweepable laser source

      Wavelength sweepable laser source
      Wavelength sweepable laser source is disclosed, wherein the laser source is a semiconductor laser source adapted for generating laser light at a lasing wavelength. The laser source comprises a substrate, a first reflector, and a second reflector. The first and second reflector together defines an optical cavity, and are arranged to support light oscillation in the optical cavity along an optical path in a direction normal to the substrate. The ...

    9. Optical tissue clearing improves usability of optical coherence tomography (OCT) for high-throughput analysis of the internal structure and 3D morphology of small biological objects such as vertebrate embryos

      Optical tissue clearing improves usability of optical coherence tomography (OCT) for high-throughput analysis of the internal structure and 3D morphology of small biological objects such as vertebrate embryos
      Developmental biology studies frequently require rapid analysis of the morphology of a large number of embryos (highthroughput analysis). Conventional microscopic analysis is time-consuming and, therefore, is not well suited for highthroughput analysis. OCT facilitates rapid generation of optical sections through small biological objects at high resolutions. However, due to light scattering within biological tissues, the quality of OCT images drops significantly with increasing penetration depth of the light beam. We ...
