Rof Intensity Modulator thin film lithium niobate modulator 20G TFLN modulator

Short Description:

The ROF-TFLN-20G series electro-optic intensity modulator is based on thin film lithium niobate waveguide technology and M-Z push-pull structure, with low half wave voltage and high operating bandwidth. The bias (DC) end adopts thermal tuning method, which can greatly reduce temperature drift and work stably for a long time at any operating point. Compared with bulk modulators, it has a smaller volume, lower power consumption, and better stability.
