We present results on optical crosstalk in the photonic integration platform developed at Fraunhofer HHI.

We employ spectrally filtered amplified spontaneous emission as the signal carrier and matched local oscillator to mitigate optical crosstalk.

A new, low cost version of the ODL(R) 125 Optical Data Link has been developed in response to market needs.

We challenge the current thinking about "Optical Internetworking" by outlining a path to Optical Data Networking that includes multiple data networking protocols and an optical networking infrastru

Optical delay lines have some important applications, notably in optical communication systems and in phase arrays.

Stimulated Brillouin scattering is used as a narrowband amplifier to demodulate and amplify FSK signals at bit rates up to 250 Mb/s.

A semiconductor laser amplifier (SLA) has been employed successfully for optical demultiplexing in two-channel optical time division multiplexed system experiments at 6 Gb/s and 2 Gb/s.

A description of optical dephasing in inorganic glasses is presented which implicates low-energy atomic tunneling systems as the dominant contributor below 1K.

We report optical dephasing of two-dimensional excitons in GaAs-AlGaAS single quantum wells by means of time-resolved Degenerate-Four-Wave Mixing and transmission experiments in the temperature ran

Microscopic photoluminescence images were measured on a dilute two-dimensional electron gas (2DEG) in an n-type modulation doped quantum well at 5K.
