LISA is set to revolutionize our understanding of the gravitational universe and the interactions that make the entire cosmos ...

For example, a milliwatt laser focus translated through the 3D volume of a holographic photopolymer writes an optical waveguide with a cross section related to the size, shape, speed and velocity of ...

Photolithography and etching are used to form the laser waveguide, and emission is parallel to the plane of the wafer surface. The typical chip length of such devices is 500 μm to 2 mm ...

A high brightness laser beam requires both high emission power from the semiconductor and a high-quality beam, he explains. And in ridge-waveguide lasers, emission power and the quality of the ...
