We demonstrate a monolithic tunable dual-wavelength laser fabricated on erbium-doped lithium niobate an insulator (Er:LNOI). The enables independent tuning with continuously linear electro-optic (EO)-modulated range of 11.875 GHz at efficiency 0.63 pm/V. Tunable microwave generation within 50 maximum extinction ratio 35 dB is experimentally demonstrated by further exploring the charge accumulation effect in LNOI. design this work paves way for microscale integration devices, presenting significant prospects photonics research and applications.
