We design and experimentally demonstrate compact and robust adiabaticity engineered couplers (AECs) with design intended splitting ratios (SRs) for the silicon-on-insulator platform. Adiabatic couplers (ACs) with variable SRs can be designed by outpu

We demonstrate a compact and broadband polarization independent 3-dB coupler for the O-band on silicon-on-insulator platform. Using the multi-parameter adiabaticity engineering protocol, unwanted coupling between eigenmodes in mode evolution couplers

Bending the axis of a waveguide coupler can result in phase mismatch between the evanescently coupled waveguides. Using a bent waveguide coupler, we realize a shortcut to adiabatic light transfer between waveguides with a sign flip of the phase misma

Bending the axis of an optical directional coupler can result in phase mismatch between the evanescently coupled waveguides. Using a quadratic bending profile, we realize the phase mismatch with a sign flip scheme for robust light coupling between th

We demonstrate a quasi-adiabatic polarization-independent 2×2 3 dB coupler based on the silicon-on-insulator platform. Using a quasi-adiabatic taper design for the mode evolution/coupling region, the TE mode evolution is accelerated, and the TM mode

A shortcut to adiabatic light transfer in mode-evolution coupler by axis bending is proposed. Phase mismatch due to waveguide width difference can be cancelled by a proper bending profile, realizing shortcut to adiabatic light transfer in the coupler

Mode conversion can be achieved in multimode waveguides using optical analogy of stimulated Raman adiabatic passage. The coupled mode equations (CMEs) for adiabatic mode conversion via an intermediate mode with wavelength detunings are derived for an

Multi-wavelength adiabaticity engineering is utilized in optical waveguides to design an ultra-broadband silicon polarization splitter-rotator. A 141μm-long device exhibits excellent performance with >97% transmission and >16 dB extinction ratio ove
