Kramers-Kronig (KK) receiver shows strong feasibility since the phase can be extracted from the detected intensity through the Hilbert transform (HT). To reduce the complexity and make the HT more …
The spectroscopic properties of Er 3+ -doped tellurite glasses were investigated and a 1 wt.% Er 3+ -doped tellurite fiber was fabricated for L-band lasers. Wavelength-tunable fiber lasers in a lin…
