An optical source of microwaves with very low phase noise for communications and radar systems is realized and tested. It is obtained by dual-frequency operation of a diode pumped Er,Yb:glass laser.

A laser scanner can help in continuous imaging without touching or squeezing the object 7,8,9; it is simple and flexible to operate and harmless to the human body, with a wide irradiation area to ...

For the first time we demonstrate an anti-colliding mode-locked laser implemented on a III-V-on-silicon platform. In passive mode-locked operation a 1.7kHz 3dB linewidth of the fundamental RF tone at ...
