Thanks to their wavelength diversity and to their excellent uniformity, Quantum well infrared photodetectors (QWIP) emerge as potential candidates for astronomical or defense applications in the ve

Let h( ·) be an integrable f u n c t i o n of integral u n i t y , vanishing for negative a r g u m e n t ; let a, to, a n d # ( 0 ) be c o n s t a n t s ; a n d let / ( · ) be a periodic f u n c t

We demonstrated ultra compact waveguide UTC photodiode with bandwidth efficiency product of 36 GHz on50 Ohm load and above 54 GHzon 25 Ohm load, which allow to reach a bandwidth above 110 GHz with

HBT power technology offers an excellent compromise for high power and high efficiency amplifiers up to the Ku band.

In this work, we have proposed a new class of planar microwave passive components, which are ultra stable in frequency with temperature for different applications, such as resonators, filters, osci

This paper will review the progresses in high capacity submarine transmission systems and the key technologies used to increase channel bit rate as well as fiber capacity.

Since the demonstration of 100Gb/s coherent for transoceanic systems in 2009, the capacity reported in record experiments continue to raise.
