Mode-division multiplexing (MDM) has been extensively exploited to expand the capacity of chip-scale optical interconnects, whereas high-volume manufacturing on-chip mode (de)multiplexers is still full challenges.

The presented could eliminate mismatch hybridization caused by errors. When sidewall are 0°, 5°, width 0, ±...
The mode-division multiplexing technology has been developing slowly in the field of fiber-chip-fiber optical interconnects, mainly limited by inefficient mode coupling between few-mode fiber and multi-mode photonic chip. Here we propose design a coupler composed tapered silicon integrated multistage waveguide tapers, which allows direct high-order modes with high efficiency low crosstalk. Based on edge scheme, six linear polarization (LP01x/y, LP11ax/y, LP11bx/y) are firstly coupled into...
Exceptional points (EPs) are degeneracies of two or more eigenstates and eigenvalues in non-Hermitian systems, promising applications optoelectronics. In particular, chiral state conversion can be achieved by dynamic encircling an EP to enable backward-scattering light isolation asymmetric mode switching. However, critical bottlenecks have plagued most mainstream EP-based converters, since they mainly use the traditional dual-coupled waveguide systems for parametric tuning as essential part...

We experimentally demonstrate a silicon chiral mode switching device by dynamically encircling exceptional point at 2 μm waveband, with high purities (> 95%) for both TE 0 and 1 modes in broad bandwidth (85 nm).
Abstract Dynamically encircling exceptional points (EPs) in non‐Hermitian systems has garnered considerable attention for enabling chiral mode switching, where the nature of output is determined solely by handedness. However, typical transmission devices primarily operate within 1.55 µm waveband and encounter wavelength‐dependent mismatch, which constrains operational range degrades purity. In this study, we address these limitations introducing metamaterial waveguides to tailor requisite...
