Singlemode chalcogenide fiber infrared SNOM probes

Giorgio Margaritondo

We have fabricated and tested infrared scanning near-field optical microscope (IR-SNOM) probe tips made from singlemode chalcogenide fiber. The process used to create the tips was similar to conventional micropipette-puller techniques, with some modificati ...

Glass fiber catalysts for total oxidation of CO and hydrocarbons in waste gases

Albert Renken, Lioubov Kiwi

Different glass fibers in woven forms were used as supports for Pt and Pd catalysts and were tested in toluene and CO total oxidn. at atm. pressure. The catalytic activity and the ignition-extinction temps. were investigated in relation to chem. compn. of ...

Optical fibers with patterned ZnO/electrode coatings for flexural actuators

Nava Setter

A fiber-based flexural actuator was developed using a patterned piezoelectric ZnO/electrode fiber coating on a standard telecommunications optical fiber. The actuator was composed of a concentric inner Cr/Au electrode, a thick sputtered ZnO coating, and an ...

Stable picosecond pulse generation at 1.3 µm in a Pr3+-doped all-fiber laser actively mode-locked using a novel fiber-optic phase modulator

René Salathé, Hans Georg Limberger

Rare-earth doped fibers can be used to realize simple, compact sources of ultrashort pulses. To date, considerable effort has been developed to obtain short pulse generation in Er3+-doped fiber lasers at 1.55 µm. Contrary to this, little work has bee ...

Development of a bioprocess for murine dimeric IgA production

Urs von Stockar

Monoclonal IgA was produced under serum free conditions by a murine hybridoma cell line (ZAC3) in a hollow fiber, a continuous stirred tank and a fluidized bed reactor. Differences in the antibody adsorption to DEAE chromatog. matrixes, an essential step i ...

New multichannel Ethernet protocol for passive optical star local area networks using coherent transmission

Philippe Robert, Hector Garcia, Caroline Brisson

A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...

Efficient active Bragg grating tunable filters

René Salathé, Hans Georg Limberger

Reflection, transmission and loss filters based on fiber Bragg gratings are key components in future wavelength division multiplexing telecommunication networks. A shift of the Bragg wavelength, λg, can be achieved by applying a strain or heating th ...
