Abstract

An integrated optical waveguide ring resonator filter in which the ring resonator structure is fabricated on Er 2+/Yb 3+-co-doped phosphate glass using ion-exchanged techniques is proposed. This approach uses ion-exchange techniques to fabricate the integrated waveguide ring resonator filter, rendering a theoretical assessment of the filter characteristics and providing a new way to design a lossless ring filter. The bend loss changes with bend radius and the waveguide dimension, both of which dramatically affect the filter performance. By changing the round-trip optical round-trip length, a different free spectrum range (FSR) and spectrum width can be obtained. An ideal lossless ring filter can be fabricated on Er 3+/Yb 3+-codoped phosphate glass using ion-exchanged techniques to produce ideal loss cancellation.
