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...
متن کاملIntegrated mode-evolution-based polarization splitter.
A mode-evolution-based polarization splitter suitable for high-index-contrast systems and directly integratable with a recently reported on-polarization rotator is described and its performance verified through both finite-difference time-domain and eigenmode expansion simulations. For a device length of 200 microm, greater than 22 dB of extinction is obtained across a 1.45-1.75-microm bandwidth.
متن کاملA 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...
متن کاملTaper-integrated multimode-interference based crossings for silicon wire waveguides
Novel multimode-interference (MMI)-based crossings integrated with miniaturized tapers are numerically presented for Silicon wire waveguides. These miniature tapers function as field expanders to reduce transition loss between the input/output waveguide and the MMI region and the crosstalk in the crossing section. As a consequence, the lengths of MMI sections reduce to less than twice of the be...
متن کاملGaussian beam shaping based on multimode interference
Laser beam transformation utilizing the effect of multimode interference in multimode (MM) optical fiber is thoroughly investigated. When a Gaussian beam is launched to an MM fiber, multiple eigenmodes of the MM fiber are excited. Due to interference of the excited modes, optical fields that vary with the MM fiber length and the signal wavelength are generated at the output facet of the MM fibe...
