  • Experimental Demonstration of Frequency Autolocking an Optical Cavity Using a Time-Varying Kalman Filter 
    Schütte, Dirk; Hassen, S.Z. Sayed; Karvinen, Kai S.; Boyson, Toby K.; Kallapur, Abhijit G.; Song, Hongbin; Petersen, Ian R.; Huntington, Elanor H.; Huntington, Elanor H.; Heurs, Michèle (College Park, MD : American Physical Society, 2016)
    We propose and demonstrate a new autolocking scheme using a three-mirror ring cavity consisting of a linear quadratic regulator and a time-varying Kalman filter. Our technique does not require a frequency scan to acquire ...
  • Independent tuning of excitonic emission energy and decay time in single semiconductor quantum dots 
    Höfer, B.; Zhang, J.; Wildmann, J.; Zallo, E.; Trotta, R.; Ding, Fei; Rastelli, A.; Schmidt, O.G. (College Park, ML : American Institute of Physics Inc., 2017)
    Independent tuning of emission energy and decay time of neutral excitons confined in single self-assembled In(Ga)As/GaAs quantum dots is achieved by simultaneously employing vertical electric fields and lateral biaxial ...
  • Non-local ductile damage formulations for sheet bulk metal forming 
    Beese, Steffen; Loehnert, Stefan; Wriggers, Peter (Bristol : Institute of Physics Publishing, 2016)
    A ductile damage model for sheet bulk metal forming processes and its efficient and accurate treatment in the context of the Finite Element Method is presented. The damage is introduced as a non-local field to overcome ...
  • Optimising process efficiency during remote laser cutting of CFRP by utilisation of a double-scan-head 
    Dittmar, Hagen; Herda, Patrick; Jäschke, Peter; Suttmann, Oliver; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2016)
    A double-scan-head was developed combining two pairs of galvo-mirrors into one device. One pair controls the laser beam's position, while the other in this setup is used for a pyrometer. Thus, a pyrometer's optical path ...
  • A simulation of weak-light phase-locking for space laser interferometer 
    Li, Y.Q.; Dong, Y.H.; Liu, H.S.; Luo, Z.R.; Jin, G. (Bristol : Institute of Physics Publishing, 2017)
    A simulation was investigated to better understand the impacts and effects of the additional technical noises on weak-light phase-locking for space laser interferometer. The result showed that the locking precision was ...
  • The size-selective interaction of key and lock nanocrystals driven by depletion attraction at the nanoscale 
    Hinrichs, D.; Himstedt, R.; Dorfs, Dirk (Cambridge : Royal Society of Chemistry, 2018)
    In this article, we study the size-dependent interactions of quasi-spherical nanocrystals with voids of concave nanoparticles of complementary sizes and shapes. Experimental insights into a system with key and lock particles ...
  • Utilizing weak pump depletion to stabilize squeezed vacuum states 
    Denker, T.; Schütte, D.; Wimmer, M.H.; Wheatley, T.A.; Huntington, E.H.; Heurs, Michèle (Washington, DC : The Optical Society, 2015)
    We propose and demonstrate a pump-phase locking technique that makes use of weak pump depletion (WPD) - an unavoidable effect that is usually neglected - in a sub-threshold optical parametric oscillator (OPO). We show that ...
