TM MODE ANALYSIS OF POLYMERIC Y-JUNCTION WAVEGUIDE

摘要：

The theoretical analysis of the TM mode lightwave propagation and loss characteristics of the Y-Junction waveguide structure is carried out using the Effective Index Method (EIM) and two-dimensional (2-D) Finite Difference Beam Propagation Method (FD-BPM). The large refractive index step between consecutive polymer layers is reduced by using EIM and thus the precision of the calculation is ensured. Important parameters of the waveguide are discussed and their relationships with the optical power propagation and loss characteristics are investigated in this paper. The total loss we obtained from the optimized structure is ～0.168 dB.
