      A novel application of chirped dielectric mirrors for narrow beam focalization is proposed and demonstrated numerically and experimentally. Analogy to temporal dispersion compensation by chirped dielectric mirrors is discussed.
    • Beam focusing in chirped mirror with a defect 

      Cheng, Yu Chieh; Staliunas, Kestutis (IEEE Press ; Wiley, 2004)
      Conference report

    • Development of a design and optimization tool for axial mirror supports of large telescopes 

      Blanco Bravo, Iker; Casamor Martinell, Oriol; Marzoa Domínguez, Antonio (2023-02)
      Article
      Open Access
      The present paper describes a parametric design and optimization tool [Support Optimization and Design Tool (SODT)], used to evaluate passive axial support positions on circular solid meniscus mirrors. The developed tool ...
    • Diseño del proceso de fabricación de un nuevo sistema retrovisor instalable en el interior del automóvil 

      Recio Pascual, Héctor (Universitat Politècnica de Catalunya, 2007-04)
      Master thesis (pre-Bologna period)
      Open Access
      En el presente documento se estudia el proceso de fabricación de un nuevo sistema retrovisor instalable en el interior del automóvil. Se inicia con una descripción del diseño del retrovisor que se realizó con anterioridad ...
    • Flat focusing mirror 

      Cheng, Yu Chieh; Kicas, Simonas; Trull Silvestre, José Francisco; Peckus, Martynas; Cojocaru, Crina; Vilaseca Alavedra, Ramon; Drazdys, Ramutis; Staliunas, Kestutis (MACMILLAN PUBLISHERS LIMITED, 2014-09-17)
      Article
      Open Access
      The control of spatial propagation properties of narrow light beams such as divergence, focusing or imaging are main objectives in optics and photonics. In this letter, we propose and demonstrate experimentally a flat ...
    • Flat focusing mirrors 

      Staliunas, Kestutis; Cheng, Yu-Chiech; Kicas, Simonas; Trull Silvestre, José Francisco; Cojocaru, Crina; Peckus, Martynas; Vilaseca Alavedra, Ramon; Drazdys, Ramutis (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Conference report
      Restricted access - publisher's policy
      We present the flat focusing mirror - the dielectric mirrors capable to focus and image the narrow beams in reflections. The mirrors are flat, and transversally invariant, i.e. have no optical axis. We consider two different ...
    • Modes in microchip lasers 

      Plukys, Matas; Gaizauskas, Eugenijus; Gailevicius, Darius; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
      Conference report
      Restricted access - publisher's policy
      The transverse modes in microchip lasers (MCL) appear different from the classical mode theory, as the resonator consists of a set of plane mirrors (similar to semiconductor edge-emitting lasers and VCSELs). Then the ...
    • Out of band improved performance into a measured 5G N77 band transversal filter 

      Udaondo Guerrero, Carlos; Collado Gómez, Juan Carlos; Mateu Mateu, Jordi; Perea Robles, Rafael; Yusud, Yazid; Giménez Bonastre, Alfred Raul; Aigner, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Restricted access - publisher's policy
      Transversal networks for electroacoustic filters had been proposed and manufactured recently. One of the main problems that arose in the first prototype were the spurious modes due to the mirror stack of the Solidly Mounted ...
    • Strategy to obtain initial configurations for free form reflectors design

    • Structured Meta-Mirrors for Beam Spatial Filtering 

      Herrero Simon, Ramon; Wang, Pey-Yu; Botey Cumella, Muriel; Cheng, Yu-Chieh; Staliunas, Kestutis (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference report
      Open Access
      The work presents optical spatial filtering in reflection based on translationally invariant meta-mirrors. The meta-structure is generated by a thin grating presenting a transverse modulation of the refraction index on the ...
    • Translationally invariant metamirrors for spatial filtering of light beams

      Article
      Open Access
      We propose a translationally invariant metamirror for light filtering in reflection. The device consists of athin transverse grating in the micron scale positioned in front of a flat mirror. We analyze the performance ...
