Design and performance evaluation of 1-by-64 multimode interference power splitter for optical communications

Ultracompact photonic crystal polarization beam splitter based on multimode interference.

We propose a theoretical design for a compact photonic crystal (PC) polarization beam splitter (PBS) based on the multimode interference (MMI) effect. The size of a conventional MMI device designed by the self-imaging principle is not compact enough; therefore, we design a compact PC PBS based on the difference of the interference effect between TE and TM modes. Within the MMI coupler, the depe...

1x12 Even Fanout Using Multimode Interference Optical Beam Splitter on Silicon Nanomembrane

All-Optical Reconfigurable-Tunable 1×N Power Splitter Using Soliton Breakup

In this paper, we numerically simulated a glass-based all-optical 1×N power splitter with eleven different configurations using soliton breakup in a nonlinear medium. It is shown that in addition to reconfigurability of the proposed splitter, its power splitting ratio is tunable up to some extent values too. Nonlinear semivectorial iterative finite difference beam propagation method (IFD-...

A Photonic 1 × 4 Power Splitter Based on Multimode Interference in Silicon–Gallium-Nitride Slot Waveguide Structures

In this paper, a design for a 1 × 4 optical power splitter based on the multimode interference (MMI) coupler in a silicon (Si)-gallium nitride (GaN) slot waveguide structure is presented-to our knowledge, for the first time. Si and GaN were found as suitable materials for the slot waveguide structure. Numerical optimizations were carried out on the device parameters using the full vectorial-bea...

Received Optical Power Calculations for Optical Communications Link Performance Analysis

The factors affecting optical communication link performance differ substantially from those at microwave frequencies, due to the drastically differing technologies, modulation formats, and effects o f quantum noise in optical communications. In addition, detailed design control table calculations for optical systems are less well developed than corresponding microwave system techniques, reflec...
