Journal ArticleDOI
Semiconductor saturable absorber mirrors (SESAM's) for femtosecond to nanosecond pulse generation in solid-state lasers
Ursula Keller,K.J. Weingarten,Franz X. Kärtner,D. Kopf,B. Braun,I.D. Jung,R. Fluck,C. Honninger,Nicolai Matuschek,J. Aus der Au +9 more
TL;DR: In this paper, the design requirements of SESAM's for stable pulse generation in both the mode-locked and Q-switched regime were reviewed, and the combination of device structure and material parameters provided sufficient design freedom to choose key parameters such as recovery time, saturation intensity, and saturation fluence.
Journal ArticleDOI
In vivo ultrahigh-resolution optical coherence tomography.
Wolfgang Drexler,Uwe Morgner,Franz X. Kärtner,Costas Pitris,Stephen A. Boppart,Xingde Li,Erich P. Ippen,James G. Fujimoto +7 more
TL;DR: To overcome depth-of-field limitations the authors perform zone focusing and image fusion to construct a tomogram with high transverse resolution throughout the image depth, which is to their knowledge the highest longitudinal resolution demonstrated to date for in vivo OCT imaging.
Journal ArticleDOI
Ultrahigh-resolution ophthalmic optical coherence tomography
Wolfgang Drexler,Uwe Morgner,Ravi K. Ghanta,Franz X. Kärtner,Joel S. Schuman,James G. Fujimoto +5 more
TL;DR: New technology for optical coherence tomography (OCT) that enables ultrahigh-resolution, non-invasive in vivo ophthalmologic imaging of retinal and corneal morphology with an axial resolution of 2–3 μm is presented, which is, to the authors' knowledge, the highest resolution for in vivo OCT imaging achieved to date.
Journal ArticleDOI
Spectroscopic optical coherence tomography.
Uwe Morgner,Wolfgang Drexler,Franz X. Kärtner,Xingde Li,Costas Pitris,Erich P. Ippen,James G. Fujimoto +6 more
TL;DR: Spectroscopic optical coherence tomography (OCT) as discussed by the authors is an extension of conventional OCT for performing cross-sectional tomographic and spectroscopic imaging, which allows the spectrum of backscattered light to be measured over the entire available optical bandwidth simultaneously in a single measurement.
Journal ArticleDOI
Polarization-transparent microphotonic devices in the strong confinement limit
Tymon Barwicz,Michael R. Watts,Michael R. Watts,Miloš A. Popovi cacute,Peter T. Rakich,Luciano Socci,Franz X. Kärtner,Erich P. Ippen,Henry I. Smith +8 more
TL;DR: In this article, the first polarization-transparent add-drop filter from polarization-sensitive microring resonators is presented, which shows almost complete elimination of polarization sensitivity over the 60nm bandwidth measured, while maintaining outstanding filter performance.
