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
Photonic-bandgap microcavities in optical waveguides
James Foresi,Pierre R. Villeneuve,J. Ferrera,E.R. Thoen,Günter Steinmeyer,Shanhui Fan,John D. Joannopoulos,Lionel C. Kimerling,Henry I. Smith,Erich P. Ippen +9 more
TL;DR: In this paper, the authors measured microcavity resonances in two-and three-dimensional photonic-bandgap (PBG) structures integrated directly into a sub-micrometre-scale silicon waveguide.
Journal ArticleDOI
77-fs pulse generation from a stretched-pulse mode-locked all-fiber ring laser
TL;DR: By incorporating a section of large positive-dispersion fiber in an all-fiber erbium ring laser, a fully self-starting source of 77-fs pulse with 90 pJ of energy and greater than 1 kW of peak power at a 45-MHz repetition rate is obtained.
Journal ArticleDOI
Theory for displacive excitation of coherent phonons.
TL;DR: Experiments in semimetals and semiconductors that show large-amplitude oscillations with periods characteristic of lattice vibrations, and a theory of the excitation process in this class of materials is presented, which is referred to as displacive excitation of coherent phonons (DECP).
Journal ArticleDOI
Ultrashort-pulse fiber ring lasers
TL;DR: In this article, the passive mode-locking technique of polarization additive pulse mode locking (P-APM) is used to generate stable, self- starting, sub-500 fs pulses at the fundamental repetition rate from a unidirectional fiber ring laser operating in the soliton regime.
