We report on the design and characterization of a high-power and high dynamic range directly modulated analog fiber optic link in the S (2–4 GHz) band. The link is amplifier free, and uses passive impedance matching networks associated to high power laser diode and high power photodiode. Thanks to the high components efficiencies, together with the benefit of reactive impedance matchings, we achieved...
We first report on a high average output power (>3dBm) 1.55μm EML TOSA able to address industrial environment temperature range [−40/+90°C] with Ultra-Low Power consumption (0.8W) and power penalty <2dB over 100km SMF fiber transmission.
Experimental demonstration of a bit rate as high as 32 Gbit/s is achieved over 20 km SMF for NGPON in a temperature range of 5??C-60??C using AMOOFDM direct modulation of a linear laser.
1550 nm AlGaInAs DFB lasers and PIN receptors were developed for analog transmission up to 20 GHz. Over 20 GHz bandwidth are measured for both laser and detector. Highly linear characteristics and low RIN < -150 dB/Hz have been obtained for lasers.
We present the first results of transmission up to 80°C over 100 km of standard fiber using an integrated electro-absorption modulator lasers. This enables uncooled small form factor metropolitan transmitters.
Phonon dispersion curves, far-IR and low-frequency Raman spectra (below 200 cm -1 ) of 4-nitro-pyridine N-oxide (NPO) including results at high pressure and low temperature are reported and interpreted with the help of a lattice-dynamical calculation using atom-atom Buckingham-type potentials and a multipole expansion up to the quadrupole. The charge transfer process is analysed through...
