In a significant advance on exploring the fascinating world of photonic structures, this study by Aeschlimann et al. elegantly blends the rigorous experimental technique of photoemission electron microscopy (PEEM) with the sophistication of finite-difference time-domain simulations to uncover the photonic band-edge states in golden Vogel spiral structures. These two-dimensional structures, which are inspired by the captivating pattern observed in the head of sunflowers, have been produced in the laboratory through the precise milling of nano-holes in a silicon film. Through the innovative use of femtosecond laser pulses, the authors expertly reveal elusive dynamics within these complex structures, potentially paving the way for new explorations of light-localization phenomena and orbital angular-momentum photonic modes. This work demonstrates the capabilities of PEEM in investigating electromagnetic modes in photonic structures and underscores the potential of Vogel spirals in manipulating and harnessing light's properties, promising an exciting frontier for future research. Beyond these methodological contributions, their findings open up intriguing possibilities for understanding ordered, disordered, and aperiodic photonic structures, illuminating the path towards novel photonic devices and applications inspired by the beauty of nature's mathematics.
