Abstract: Bismuth doped fiber amplifiers (BDFA) have been pumped with single mode 1190–1260 nm lasers to amplify signals over the O-band. We report here a BDFA using 915 nm multimode laser via an ...
Abstract: This letter proposes a robust approach for developing a new class of electrically reconfigurable phase shifter. This design employs via posts on substrate integrated waveguide (SIW) ...
