Supercontinuum generation in silicon Bragg grating waveguide
Neetesh Singh, Manan Raval, Erich Ippen +2
Supercontinuum generation is an extensively studied and arguably the most important and all-encompassing nonlinear phenomenon. Yet, we do not have a good control over all the signa…
Towards CW modelocked laser on chip -- large mode area and NLI for stretched pulse mode locking
Neetesh Singh, Erich Ippen, Franz X. Kärtner
Integrated modelocked lasers with high power are of utmost importance for next generation optical systems that can be field-deployable and mass produced. Here we study fully integr…
Supercontinuum generation in varying-dispersion and birefringent silicon waveguide
Neetesh Singh, Diedrik Vermulen, Alfonso Ruocco +4
Ability to selectively enhance the amplitude and maintain high coherence of the supercontinuum signal with long pulses is gaining significance. In this work an extra degree of free…
Theory of THz generation by Optical Rectification using Tilted-Pulse-Fronts
Koustuban Ravi, Wenqian Ronny Huang, Sergio Carbajo +4
A model for THz generation by optical rectification using tilted-pulse-fronts is developed. It simultaneously accounts for (i) the spatio-temporal distortions of the optical pump p…
220 fs Er-Yb:glass laser mode-locked by a broadband low-loss Si/Ge saturable absorber
F. J. Grawert, S. Akiyama, F. O. Ilday +7
We demonstrate femtosecond performance of an ultra-broadband high-index-contrast saturable Bragg reflector consisting of a silicon/silicon-dioxide/germanium structure that is fully…
