“…Numerical simulation has been widely used in the design optimization of optoelectronic devices, since it can save tremendous labor and cost before fabrication. Many of these simulations are performed in the frequency domain, for example using a numerical approach such as the Finite Difference Beam Propagation Method (FD BPM), [1][2][3], or a semi-analytic approach such as the Spectral Index (SI) Method, [4][5]. These methods obtain the continuous wave (CW) response of the device for a fixed frequency, and may make physically consistent approximations for a particular class of device.…”

Multimode interference (MMI) devices have been developed for a large number of optoelectronic applications. Frequency domain methods have been widely used to simulate the behavior of this class of device at fixed operating wavelengths. However time domain models are becoming more popular in photonic simulation as bandwidths increase and account needs to be taken of material properties such as nonlinearity. By making physically consistent approximations, the time-domain beam propagation method provides simulation without incurring the large memory and computational penalties of other time domain numerical methods. In this paper we will compare these various approaches in the context of simulating MMI devices, provide guidelines for the selection of one approach in preference to the other and discuss the limitations and errors introduced by some of the common approximations made.

“…The refractive-index profile of the waveguide is characterized by three relative index heights L = (n -n)/2n for i = 2,3,4. To search for the zero-birefringence conditions for this waveguide, we apply the spectral index method developed for multi-layer structures 18. To reduce the number of variables, we assume L2 = 0.01 and = 0.45, which are typical values for air-clad semiconductor waveguides.…”

Polarization dependence is a major factor of consideration in the design of optical waveguide devices for applications in optical fiber transmission systems. In many cases, the polarization-dependence problem can be solved by using waveguides with zero modal birefringence. In this paper, theoretical results are presented to show how zero-birefringence waveguides can be designed from various waveguide geometries. The waveguides considered in this paper include strip waveguides, rib waveguides, strip-loaded waveguides, and multiple-quantum-well waveguides, which are of particular importance in the construction of semiconductor-based photonic integrated circuits . The design of p olarization-insensitive directional couplers with rib waveguides is also discussed.
