An Integrated Pump-Controlled Variable Coupler Fabricated by Ultrafast Laser Writing
The design and fabrication of a integrated symmetric directional coupler dependent o the pumping power and operating at a 1534 nm wavelength is reported. The twin-core waveguide was inscribed into Er(3+)/Yb(3+) co-doped phosphate glass by a femtosecond laser direct writing technique. By optical pump...
