Abstract
We demonstrate an on-chip electro-optically tunable Fabry-Perot (FP) cavity laser on Er3+-doped thin film lithium niobate (Er: TFLN). The FP cavity consists of two Sagnac loop reflectors at the two ends with a loaded quality factor of 1.3 × 105 and a free spectral range of 68 pm. The fabricated Er: TFLN FP laser structure is integrated with microelectrodes designed for electro-optically tuning, and a continuous laser wavelength tuning with 24 pm around 1544 nm is achieved by applying a driving voltage from −6 V to 6 V.
