3-port Fiber-coupled AO Modulator

Fiber-Coupled AO Modulators

Brimrose’s all‑fiber, electronically controlled Fiber-Coupled AO Modulators (AOMs) adjust light amplitude, pulse duration, and frequency. Typical uses include switching, pulse picking, and fast attenuation across wavelengths from near‑UV to near‑IR.

We also offer a specialized type of modulator—the programmable attenuator. Attenuators are essential in fiber‑optic systems because they control and adjust the strength of the light signal. They match optical power to receiver dynamic range, set input/output levels in EDFAs, balance power across DWDM channels, and evaluate system performance under different optical power conditions.


Performance Capabilities

Fiber-Coupled AOMs deliver low insertion loss, high extinction ratios (up to 70 dB), fast rise times, and operation at frequencies up to several hundred MHz to enable precise, high-performance optical signal and power control in advanced photonic systems, with customizable configurations to meet application-specific requirements.
