The first includes an integrated coupler, two arms each containing someimplementation of the end-reflector, and a phase bias element in one arm. The second includes an integrated directional coupler, twointegrated waveguide arms, and another integrated coupler as an output. The third includes an integrated birefringent element, integratedbirefringent-free waveguide, and integrated polarizer. And the fourth includes a multimode waveguide that allows for different modes © to propagate in such a way that the difference in the spatial distribution of intensity causes a nonlinear phase difference between the00 modes. These are just some examples of an on-chip fully integrated artificial saturable absorber with instantaneous recovery time thatf , allow for generation of sub-femtosecond optical pulses at high repetition rates using passive mode-locking. 000472530 536__ $$0G:(DE-HGF)POF4-631$$a631 - Matter – Dynamics, Mechanisms and Control (POF4-631)$$cPOF4-631$$fPOF IV$$x0 000472530 693__ $$0EXP:(DE-H253)CFEL-Exp-20150101$$5EXP:(DE-H253)CFEL-Exp-20150101$$eExperiments at CFEL$$x0 000472530 7001_ $$0P:(DE-H253)PIP1013198$$aKärtner, Franz$$b1$$udesy 000472530 7001_ $$0P:(DE-H253)PIP1017800$$aCallahan, Patrick Timothy$$b2 000472530 7001_ $$0P:(DE-HGF)0$$awatts, michael$$b3 000472530 7001_ $$0P:(DE-HGF)0$$aippen, erich$$b4 000472530 8564_ $$uhttps://patentimages.storage.googleapis.com/b1/48/9d/85cbc505cf89fd/WO2018044363A3.pdf 000472530 8564_ $$uhttps://bib-pubdb1.desy.de/record/472530/files/WO2018044363A3.pdf$$yRestricted 000472530 8564_ $$uhttps://bib-pubdb1.desy.de/record/472530/files/WO2018044363A3.pdf?subformat=pdfa$$xpdfa$$yRestricted 000472530 909CO $$ooai:bib-pubdb1.desy.de:472530$$pVDB 000472530 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1017817$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000472530 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1013198$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000472530 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1013198$$aCentre for Free-Electron Laser Science$$b1$$kCFEL 000472530 9101_ $$0I:(DE-588)1043621512$$6P:(DE-H253)PIP1013198$$aEuropean XFEL$$b1$$kXFEL.EU 000472530 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1017800$$aExternal Institute$$b2$$kExtern 000472530 9131_ $$0G:(DE-HGF)POF4-631$$1G:(DE-HGF)POF4-630$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lFrom Matter to Materials and Life$$vMatter – Dynamics, Mechanisms and Control$$x0 000472530 9201_ $$0I:(DE-H253)CFEL-ULOCM-20160928$$kCFEL-ULOCM$$lFS-CFEL-2$$x0 000472530 980__ $$apatent 000472530 980__ $$aVDB 000472530 980__ $$aI:(DE-H253)CFEL-ULOCM-20160928 000472530 980__ $$aUNRESTRICTED
