Photonic-chip integrated large-mode-area high-power CW optical amplifier

Photonic-chip integrated large-mode-area high-power CW optical amplifier

Here, we report on a CMOS-compatible thulium-doped high power continuous wave (CW) optical amplifier, leveraging large mode-area gain waveguides. The amplifier structure combines a silicon nitride waveguide above which a sputtered 1250 nm-thick thulium-doped alumina gain layer is deposited. We demon...
