- Observation of two-dimensional nonlocal gap solitonsPer Dalgaard Rasmussen
Nonlinear Physics Centre, Research School of Physical Sciences and Engineering, Australian National University, Canberra, ACT, Australia
Opt Lett 34:295-7. 2009..We employ liquid-infiltrated photonic crystal fibers and show how the system geometry can modify the effective response of a nonlocal medium and the properties of two-dimensional gap solitons...
- Degenerate four wave mixing in solid core photonic bandgap fibersPer Dalgaard Rasmussen
DTU Photonics, Department of Communications, Optics and Materials, Technical University of Denmark, Ørsteds Plads 345V, DK 2800 Kgs Lyngby, Denmark
Opt Express 16:4059-68. 2008..The possibility of tuning the efficiency of the parametric gain by varying the temperature is also considered. The results are verified by numerical simulations of pulse propagation...
- Spatiotemporal control of light by Bloch-mode dispersion in multi-core fibersPer Dalgaard Rasmussen
Centre for Ultrahigh Bandwidth Devices for Optical Systems, Research School of Physical Sciences and Engineering, Australian National University, Canberra, ACT 0200, Australia
Opt Express 16:5878-91. 2008..We define the conditions for achieving anomalous group-velocity dispersion and discuss possibilities for generation of spatiotemporal solitons...
