Physicists have coaxed a cloud of quantum spins into doing something that should not happen in ordinary materials: they light up with microwaves and simply keep going. Instead of fading away, the ...

A single-fiber linear-cavity laser integrated with multifunctional devices was proposed and demonstrated for fiber dual-comb acquisition speed enhancement. This setup enabled flexible control of the ...

Fig. 1 (a) Schematic of a PM that consists of two nanobeam cavities. (b) Normalized profile of the electric field (Ex at left and Ey at right) for the S and AS mode Polarization is an intrinsic ...

Single-mode semiconductor lasers provide an inexpensive and compact laser source for a wide range of applications, including Raman spectroscopy, Raman microscopy, process Raman, metrology, atomic ...
