Study on a low loss, low voltage, polarization-independent EO modulator based LPG
Optics & Laser Technology(2007)
摘要
In this paper, a new type of high-speed EO modulator is presented. It is a multi-cladding structure with LPG written in the core, and polymer with high EO coefficient is fabricated as the outer layer. A special material with ultra-negative temperature coefficient is used for the temperature compensation. This modulator is polarization independent, it can be coupled with the optical fiber very easily and can work steadily with low voltage, high speed, is temperature insensitive, and its cost is low. To our knowledge, this is the first time a modulator has been designed with such a simple and effective structure.
