We demonstrate broadband THz modulation in liquid under the applications of suitable magnetic fields. 65% modulation has been obtained using 50mT. The modulation is polarization sensitive and achieved thanks to a magnetic-induced medium anisotropy.

We studied the photoluminescence of tensile strained germanium nanostructures. Sub-micron gratings and pillars were fabricated before being coated with strained silicon nitride films. Using different deposition conditions and different sizes of structures the stress in the nanostructures can be controlled. The measured optical properties of the samples show that the direct band-gap is shifted drastically towards higher wavelengths over 1.9 μm. This local control of the stress in germanium nanostructures opens the route for both emitters and photodetectors above 1.6 μm wavelength which are not easily available and also potentially towards a germanium laser.

A high-speed continuous-variable quantum random bit generator with an expected effective bit generation rate of up to 10 GBit/s is presented. The obtained bit sequences are truly random and unique, i.e. they cannot be known by an adversary.

Self-referencing using two adjacent 2-dimensional photonic crystals is investigated. The two resonances are shown to have nearly identical quality factors and sensitivities. A split-flow microfluidics scheme for partial functionalization or differential measurement is also demonstrated.

We report on the nonlinear response and optical bistability in the transmitted and reflected signals of Si3N4 microrings. Micro-second temporal dynamics of the response suggest that the nonlinear behavior is due to the thermo-optic effect.
