We report on the design and experimental demonstration of a substrate emitting quantum cascade laser (QCL) with low beam divergence in the two directions.
Using the asymptotic matching procedure of Dombre and Hakim, we determine properties of the steady state cellular structures with deep narrow grooves observed in directional solidification experime
To say that the market for cellular telephony is growing would be an understatement, to say the least.
TWO systematic collections of directive amplitude diagrams are shown for arrays of 2 and of 16 identical antennae spaced at equal distances along a straight line with equal phase differences introd
We demonstrate error-free performance of an MRR filtered DML on the SOI platform over 40- and 81-km of SSMF. The device operates up to 17.5 Gb/s over 81 km and 20 Gb/s over 40 km.
We propose and demonstrate asymmetric 10 Gbit/s upstream - 100 Gbit/s downstream per wavelength colorless WDM/TDM PON using a novel hybrid-silicon chip integrating two tunable lasers.
The future access networks requires to develop key innovative transmitters operating at 10Gb/s around 1550nm and capable of transmitting data in extended reach passive optical networks (>60km).
We report a novel directly reflectivity modulated laser (DRML) whose output is modulated through a Michelson interferometer reflector of the laser cavity.
Directly modulated lasers (DMLs) have been widely employed in data centers and other short-reach interconnect applications, thanks to their low cost and low power consumption.
We report a novel directly reflectivity modulated laser (DRML) allowing for phase and intensity modulation through a Michelson interferometric mirror.
