Y‑Branch Modulator
I. Product Introduction
The Y‑Branch Modulator is a multi‑function integrated optical device integrating polarization, light guiding, beam splitting, beam combining and phase modulation. It serves as a core optoelectronic component for interferometric optical‑fiber sensing systems such as fiber‑optic gyroscopes and fiber‑optic current transformers.
Fabricated on lithium‑niobate wafers via proton‑exchange process, the Y‑Branch Modulator features optical waveguides with low loss and high polarization extinction ratio. Metal thin‑films are deposited atop the waveguides to form modulation electrodes. The precisely polished modulator chip is aligned and adhesively bonded with small‑mode‑field panda‑type polarization‑maintaining fibers by high‑precision fiber alignment and high‑reliability fiber‑coupling technology.
We provide standard Y‑Branch Modulator models as listed below:
