Rare-Earth Doped Integrated Gain and Devices

With the increasing demands on the scalability and complexity of integrated photonic systems, on-chip loss has become a main obstacle preventing the total number of components to be integrated on a chip. Compared with semiconductor optical amplifier (SOA), rare-earth (RE) doped gain provides better noise performance during the signal amplification, which is key for specific applications such as comb and pulse amplification, narrow-linewidth laser, etc. Recent works have shown significant breakthrough on the RE doped amplifiers including output power (up to 145 mW), operation wavelength (from 1 μm to 2 μm) as well as noise figure (down to 5 dB). Integrated lasers based on RE doped gain have also shown great potential with linewidth down to 200 Hz and electro-optic tunability on thin-film lithium niobate platform. In this symposium, we share the recent important progress on RE doped integrated gain and devices and try to draw a clear picture how these RE-doped devices can benefit current research on photonic integration, nonlinear optics, frequency comb and quantum systems.
