Monolithically integrated active passive waveguide array fabricated on thin film lithium niobate using a single continuous photolithography process
Yuan Zhou, Yiran Zhu, Zhiwei Fang +13
We demonstrate a robust low-loss optical interface by tiling passive (i.e., without doping of active ions) thin film lithium niobate (TFLN) and active (i.e., doped with rare earth…
