Lithium Niobate Fiber Optical Modulator Auto-Bias Controller – Ensure Performance
The LNBC series bias controllers enhance the performance of intensity modulators by automatically biasing and stabilizing them at the quadrature point. This is achieved by injecting a low-frequency, low-amplitude dither signal and using built-in photodetectors to form a feedback loop for bias control. This loop helps maintain optimal performance and minimize temperature dependence. The bias is applied via an integrated microheater. The LNBC is designed for use with thin-film lithium niobate modulators that have integrated detectors and microheaters inside the modulator.
