Broadband 2 ×2 3 dB coupler based on ion-exchange in glass
摘要
Abstract
In order to meet the demand of fabrication and application of 2 ×N optical power splitters , theoretical and experimental researches were carried out for broadband integrated 2 ×2 3dB couplers.The traditional asymmetric X-junction was improved by using three-dimension beam propagation method , through simulation and design , 2 ×2 3dB couplers with low loss and wide operating bandwidth were obtained .Considering characteristics of asymmetric X-junction, the broadband 2 ×2 3dB coupler was successfully made by using Ag +-Na+ion-exchange in glass .The measurement of light spectrum, using two broadband light source with wavelength respectively in 1260nm ~1360nm and 1460nm ~1600nm, showed that the insertion loss was less than 4.0dB in the broadband range , wavelength response was relatively flat and wavelength insensitive , uniformity was less than 0.5dB.The results prove that , using the improved asymmetric X-junction combined with ion-exchange technique , broadband 2 ×2 3dB couplers with good performance can be fabricated in glass , which lays good foundation for further optimization of the device performance and successful development of its valuable application .关键词
