We have developed single frequency and single spatial mode laser structures with stable narrow linewidth (1MHz) and high optical power (40mW), using an aluminium free active region for Cs pumping a

We discuss a novel surface emitting InGaAsP LED with a relatively narrow spectrum obtained by the integral growth of a 2.6 micron thick semiconductor absorbing, or filtering, layer on a conventio

We propose and demonstrate an integrated narrow-band optical isolator in InP using two phase modulators in series. The phase modulators are driven with a single-frequency signal in quadrature.

We present the phase locking of an array of index-guided tapered laser diodes. An external cavity based on the self-imaging Talbot effect has been built.

We report an electro-optically tunable, single-frequency extended cavity laser with a linewidth of less than 60 kHz.

The Internet of Things will bring billions of devices that are inter-connected using cellular networks.

Stimulated Brillouin amplification is used for channel selection in a densely-packed WDM direct-detection lightwave experiment.

The search for traces of past and present life is a complex and multidisciplinary research activity involving several scientific heritages and a specific industrial ability for planetary exploratio
