Femtosecond pulse amplification on a chip
Mahmoud A. Gaafar, Markus Ludwig, Kai Wang +13
Femtosecond laser pulses enable the synthesis of light across the electromagnetic spectrum and provide access to ultrafast phenomena in physics, biology, and chemistry. Chip-integr…
Performance Enhancement via XPM Suppression in a Linear all-PM NPE Mode-locked Fiber Oscillator
Marvin Edelmann, Yi Hua, Mikhail Pergament +1
We demonstrate strong performance enhancement of an all polarization-maintaining fiber oscillator mode-locked using NPE in a linear self-stabilized fiber interferometer via suppres…
Octave-spanning supercontinuum generation in a CMOS-compatible thin Si3N4 waveguide coated with highly nonlinear TeO2
Hamidu M. Mbonde, Neetesh Singh, Bruno L. Segat Frare +7
Supercontinuum generation (SCG) is an important nonlinear optical process enabling broadband light sources for many applications, for which silicon nitride(Si3N4) has emerged as a…
Watt-class CMOS-compatible power amplifier
Neetesh Singh, Jan Lorenzen, Kai Wang +8
Power amplifier is becoming a critical component for integrated photonics as the integrated devices try to carve out a niche in the world of real-world applications of photonics. T…
Large Area Optical Frequency Detectors for Single-Shot Phase Readout
Felix Ritzkowsky, Matthew Yeung, Engjell Bebeti +9
Attosecond science has demonstrated that electrons can be controlled on the sub-cycle time scale of an optical wave, paving the way toward optical frequency electronics. Using cont…
Acousto-Optic Modulation in Ambient Air
Yannick Schrödel, Claas Hartmann, Tino Lang +15
Control over intensity, shape, direction, and phase of coherent light is essential in numerous fields, reaching from gravitational wave astronomy over quantum metrology and ultrafa…
Intra-Pulse Intensity Noise Shaping by Saturable Absorbers
Marvin Edelmann, Mikhail Pergament, Franz X. Kärtner
In this work, we identify and characterize intra-pulse intensity noise shaping by saturable absorbers applied in mode-locked lasers and ultra-low noise nonlinear fiber amplifiers.…
Chip-scale, CMOS-compatible, high energy passively Q-switched laser
Neetesh Singh, Jan Lorenzen, Milan Sinobad +13
Chip-scale, high-energy optical pulse generation is becoming increasingly important as we expand activities into hard to reach areas such as space and deep ocean. Q-switching of th…
A GPU-Parallelized Interpolation-Based Fast Multipole Method for the Relativistic Space-Charge Field Calculation
Yi-Kai Kan, Franz X. Kärtner, Sabine Le Borne +1
The fast multipole method (FMM) has received growing attention in the beam physics simulation. In this study, we formulate an interpolation-based FMM for the computation of the rel…
