Deep-UV-enhanced supercontinuum generated in tapered gas-filled photonic crystal fiber
Mallika Irene Suresh, Jonas Hammer, Nicolas Y. Joly +2
We present the use of linearly down-tapered gas-filled hollow-core photonic crystal fiber in a single-stage, pumped with pulses from a compact infrared laser source, to generate a…
Broadly tunable photon pair generation in a suspended-core fiber
Jonas Hammer, Maria V. Chekhova, Daniel R. Häupl +2
Nowadays fiber biphoton sources are nearly as popular as crystal-based ones. They offer a single spatial mode and easy integrability into optical networks. However, fiber sources l…
Towards third-order parametric down-conversion in optical fibers
Andrea Cavanna, Jonas Hammer, Cameron Okoth +8
Optical fibers have been considered an optimal platform for third-order parametric down-conversion since they can potentially overcome the weak third-order nonlinearity by their lo…
A Precision Angle Sensor using an Optical Lever inside a Sagnac Interferometer
J. M. Hogan, J. Hammer, S. -w. Chiow +5
We built an ultra low noise angle sensor by combining a folded optical lever and a Sagnac interferometer. The instrument has a measured noise floor of 1.3 prad / Hz^(1/2) at 2.4 kH…
