    Photonic Analog to Digital Conversion
    Digitalization of data opens unprecedented opportunities in telecommunication, radar and signal processing. Almost all sensing systems in use today require analog signals to be converted to digital ones. Signal rates have grown at a rate that has outpaced electronic analog to digital conversion (ADC). This demand for higher bandwidth, speed or digitalization precision puts stringent requirements on the aperture jitter of ADC setups.

  • Self-reference Optical Frequency Comb
    Self-reference Optical Frequency Comb
    An optical frequency comb (OFC) is a photonic tool similar to a gear in mechanics. It connects the optical frequency domain (THz) to the well-known microwave domain (MHz – GHz). This guarantees a “one to one” correspondence between frequencies that differ by more than five decades, and enables ultra-high optical frequencies to be directly resolved with standard electronics.

    Laser Surface Texturing Using a Single DOE as an Alternative for Direct Laser Interference Patternin
    In this work we introduce a simple and universal optical setup design for laser surface texturing (LST) that provides functionality superior than direct laser interference patterning (DLIP). The method requires only a single periodic diffractive optical element and a focusing lens while enabling unlimited freedom for spatial shaping and amplitude variations. The concept is based on the special be

    DOEs for beam shaping
    A diffractive optical element (DOE) uses thin micro-structure patterns to alter the phase of the light that is propagated through it. Those micro-structures once properly designed can manipulate the light to almost any desired intensity profile or shape. This technology enables many functions and light manipulations which are not feasible with standard refractive optics.

    The acousto-optical Q-switch often used in the laser marking makes use of mutual interaction between an ultrasonic wave and a light beam in a scattering medium. The light beam that enters in a direction forming a Bragg angle to the wave surface of the acoustic wave in the scattering medium is diffracted in accordance with periodic changes in the diffraction rate produced by the acoustic wave.
