Abstract:Novel on-chip devices, suitable for integrated optical applications around 1.53 µm, have been realized by applying Al2O3:Er3+ as a broad gain medium. A zero-loss optical power splitter operating over the entire C-band (1525-1565 nm) and requiring <50 mW of 977 nm pump power has been demonstrated. Peak net gain of up to 11 dB at 1532 nm and signal transmission at 170 Gbit/s without added bit-error penalty have been measured in an Al2O3:Er3+ amplifier. Finally, the first integrated Al2O3:Er3+ ring laser has been realized. Laser emission was demonstrated over the wavelength range 1530-1557 nm by tuning the output coupler length.
