By Yvonne Carts–PowellMirrors with higher power–handling capacity could enable pump lasers with higher output powers, which in turn are desirable for more powerful erbium–doped...
By Yvonne Carts–PowellA single–mode nonsilica glass holey fiber made from an extruded preform proves highly nonlinear—it has about a 500 times larger effective nonlinearity than...
By Kevin Hsu and Mark JonesAs a manufacturing tool, a WDM emulator provides a test source that includes low loss, high channel contrast, clean spectral profiles, tunability, grid...
By John DunneIt is no longer easy to decouple component and system functions or vendors. This blurring creates a new layer of responsibility—and opportunity—within the overall...
By YeeLoy LamFor the optical networking industry to repeat the success of the electronics industry, photonic design rules must be standardized and scalable device–fabrication ...
By Yvonne Carts–PowellA method of making Bragg gratings in fiber removes crosstalk–inducing sidelobes. Fiber Bragg gratings (FBGs), which act as wavelength–selective mirrors, ...
