We experimentally demonstrate a nanoscale mode converter that performs coupling
between the first two transverse electric-like modes of a silicon-on-insulator waveguide. The …

Integrated quantum optics has the potential to markedly reduce the footprint and resource
requirements of quantum information processing systems, but its practical implementation …

Mode-division multiplexing can scale the capacity of optical communications and optical
interconnects. We demonstrate an ultra-compact and fabrication-error tolerant silicon three …

We propose, design and analyze a novel mode converter in silicon waveguide based on a
graded index co-directional grating coupler. The device has a periodic variation in its …

We propose fast and robust mode conversion in multimode waveguides based on Lewis–
Riesenfeld invariant theory. The design of mode converters using the multimode driving for …

In recent years, the concept of shortcuts to adiabaticity (STA), originally developed for
speeding up slow adiabatic state evolution in quantum systems, has found numerous …

Variable power splitting ratio 2× 2 MMI couplers using multimode waveguide holograms are
analyzed. Theoretical analysis shows that variable splitting ratios can be obtained with …

This paper presents a novel fiber-optic magnetic sensor based on a side-polished fiber
Bragg grating coated with thin iron film. The Bragg wavelength shift of 0.08 nm was …

We propose and describe mode converter/splitter based on optical analogy of multistate
stimulated Raman adiabatic passage in multimode waveguides. Computer-generated …

We propose a mode converter based on adiabatic evolution of the system eigenmode. Mode
conversion is mediated by an intermediate mode that is hardly excited. The coupling …
