Abstract
A multi-channel light emitting module includes a base, at least one light emitting unit provided on the base, an optical modulation chip provided on the base, and an optical transmission component. The optical modulation chip includes an encapsulation structure and a thin film lithium niobate (LiNbOx) modulator provided in the encapsulation structure. The thin film LiNbOx modulator is optically coupled with the at least one light emitting unit, and the light emitting unit is provided outside the encapsulation structure. The optical transmission component is optically coupled with the thin film LiNbOx modulator.
