Training successfully completed: Leibniz IPHT takes on two physics lab assistants
The Leibniz Institute of Photonic Technology (Leibniz IPHT) celebrates the graduation of its trainees: Tina Keilholtz and Victoria Bohn have passed their exams as physics lab assistants with flying colors...

Fibre Bragg gratings in indium-fluoride-based fibres
The development of Mid-infrared fibre lasers has attracted the researchers’ interest due to its potential outbreaking application in several topics, for instance in biological and chemical molecular...
Research results | 16.03.2023THz Metrology
The frequency range between 100 GHz and a few THz has been used in fundamental research for many years. However, due to the lack of compact and bright sources there has long been a gap in commercial applications...
PublicationsConfocal THz Laser Microscope
We transfer the principle of the optical confocal microscope to a far-field THz imaging system based on an optically pumped gas laser emitting radiation at 2.52 THz. This results in a contrast enhancement....
PublicationsDielectric Fibres for Low-Loss Transmission of Millimetre Waves and its Application in Couplers and Splitters
We present a dielectric fibre and two splitters made of polyethylene, which are well suited for the guidance of millimeter waves. A successful construction of a 3-dB coupler and a 1×4 splitter is reported....
PublicationsA local characterization of smooth projective planes
In 2000, Bödi and Immervoll considered compact, connected smooth incidence geometries with mutually transversal point rows and tually transversal line pencils. They made the very natural assumptions the...
PublicationsHighly Accurate THz Time-Domain Spectroscopy of Multilayer Structures
We extract the optical material parameters of a layer within a multilayer sample from terahertz (THz) time-domain spectroscopy data. To this aim, we derive a suited transfer function for multilayer structures...
PublicationsHighly accurate optical material parameter determination with THz time-domain spectroscopy
We improve the existing data extraction algorithms for THz time-domain spectroscopy (THz TDS) in two aspects. On the one hand, we merge the up-to-date knowledge of THz TDS signal processing into a single...
PublicationsHighly sensitive dispersion measurement of a high-power passive optical resonator using spatial-spectral interferometry
We apply spatially and spectrally resolved interferometry to measure the complex ratio between the field circulating inside a high-finesse femtosecond enhancement cavity and the seeding field. Our simple...
