Abstract

Novel optical-waveguide mode filters, based on mode-selective coupling between nonidentical waveguides and attenuation in a lossy waveguide, are proposed and demonstrated. Both TE(0) and TM(0) mode filters were fabricated from glass compositions by rf-sputtering. For both the TE(0) and TM(0) mode filters, insertion losses were 2.1 dB and 1.1 dB, respectively, and attentuations for undesirable modes were 16.8 dB and 21.6 dB, respectively.

摘要

基于不同波导间的模式选择性耦合以及有损波导中的衰减，提出并演示了新型光波导模式滤波器。TE(0)和TM(0)模式滤波器均采用射频溅射法由玻璃成分制成。对于TE(0)和TM(0)模式滤波器，插入损耗分别为2.1 dB和1.1 dB，对不需要模式的衰减分别为16.8 dB和21.6 dB。
