A wavelength tuning scheme that outperforms thermo-optic or electro-optic techniques is revealed. A tunable waveguide mirror that operates over a giant wavelength range of 160 nm could be the key to ...

Adding slots to the chip-scale laser waveguide, which generates terahertz waves, and backing them with reflectors redirects the lost back-end output 180°, boosting the front-end output power.

Researchers have created a new process for making complex miniature waveguides that can steer optical signals in three dimensions through solid materials. All optical computers could approach the ...

Last month, this column discussed some of the fundamental concepts of selecting coaxial transmission lines. That included low-power flexible lines as well as some issues involving high-power rigid ...
