A bio array sensing system is newly composed utilizing different phospholipid liposomes encapsulating fluorescent molecules. We have confirmed a high output intensity of fluorescence emission due to the characteristics dependent on the concentration of fluorescent molecules when the fluorescent molecules leak from inside of the liposome through perturbed lipid membrane. After measuring a whole array...
The paper presents on overview of a polymer based hybrid photonic integration platform under development at HHI. The concept and technology involved are described, and recently developed components are addressed.
We present a class of devices called Asymmetric Bowtie nano-Colorsorters. These devices have specifically engineered symmetries enabling them to capture, confine, spectrally filter and steer optical fields while maintaining nanoscale field distributions.
The process of refractive index grating formation in a photorefractive crystal, used as the self-adapting spectral filter in an external cavity laser, is studied with a self-consistent model. The model is based on the Finite Difference solution of the Kukhtarev equations. The results obtained are compared with approximate analytical models.
Compact 1times2 wavelength multiplexer modules employing thin-film filters integrated into polymer planar waveguide circuits are presented. The modules also feature on-chip deep-etched U-grooves for precise fibre-chip coupling. Insertion loss <1 dB, crosstalk <-30 dB, and return loss <-50 dB have been achieved by various technological optimisations.
A 40Gb/s field trial using 12.5GHz-spaced multi-carrier 10Gb/s signals over an installed 752km WDM-link was successfully completed. Results show that the system has a superior CD and similar PMD tolerance compared to typical 10Gb/s systems.
We demonstrate 40 Gb/s SOA-based wavelength conversion from a RZ into a vestigial-sideband RZ signal. SOA related pattern effects are successfully suppressed by proper choice of the red-shift optical filter.
