An electro-optically tunable arrayed waveguide grating fabricated on thin film lithium niobate
Zhe Wang, 1 Zhiwei Fang, Yiran Zhu +6
We design and fabricate an 8-channel thin film lithium niobate (TFLN) arrayed-waveguide grating (AWG) and demonstrate the electro-optical tunability of the device. The monolithical…
An integrated electro-optically tunable multi-channel interference cavity laser
Junxia Zhou, Yiran Zhu, Botao Fu +8
We demonstrated a continuously tunable laser system by butt coupling a reflective semiconductor optical amplifier (RSOA) chip with a thin-film lithium niobate (TFLN) based multi-ch…
Integrated electro-optically tunable narrow-linewidth III-V laser
Yiran Zhu, Shupeng Yu, Zhiwei Fang +8
We demonstrate an integrated electro-optically tunable narrow-linewidth III-V laser with an output power of 738.8 μW and an intrinsic linewidth of 45.55 kHz at the C band. The lase…
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…
