Erbium-doped lithium niobate waveguide amplifier enhanced by an inverse-designed on-chip reflector
Zhiwei Wei, Jiangwei Wu, Chengyu Chen +4
This study presents a 3.6-cm-long erbium-doped lithium niobate waveguide amplifier enhanced by an inverse-designed on-chip reflector. Integrating the reflector at the waveguide end…
