Abstract
We demonstrate an 8-channel LAN wavelength division multiplexer (LWDM) on silicon-lithium niobate (Si-LN) hybrid integration platform. The device consists of three-stage cascaded MZIs. The phase-error corrections and precise wavelength alignment of 4.5 nm channel spacing are achieved by employing the electro-optic tuning effect on bonded LN waveguides on silicon. The proposed hybrid LWDM with controllable phase shifters has potential applications in optical links of ultra-large transmission capacity with integration of hybrid modulators of the same technology.
