Transverse-pressure-controlled fiber devices |
摘要 |
Implementations of a polarization control method and apparatus are provided. In one implementation, a device uses super-polished squeezing surfaces to apply pressure against a polyimide coated fiber thereby minimizing micro-bending effects that cause losses in the fiber. Special control circuitry may be used to maintain a driving source of piezo-electrics that control the squeezing surfaces at a resonant frequency, thereby minimizing the voltages needed to drive the piezo-electrics.
