We propose and experimentally demonstrate a real-time fiber-THz-fiber 2 × 2 multiple-input multiple-output (MIMO) seamless integration system at 340–510 GHz using commercial digital coherent opt…
A novel improved full-vectorial meshfree finite cloud mode solver is constructed for analysis of step-index optical waveguides with arbitrary interfaces, where the waveguide interfaces can be tilte…
Different from conventional converters only converting one given mode to a single desired one, we here propose a multi-order conversion scheme for TE 0 /TE 1 dual-mode input by exploiting asymmetri…
By using a meshless finite cloud method, a full-vector mode solver in terms of transverse-magnetic-field components for optical dielectric waveguide bends is developed in a local cylindrical coordi…
An ultracompact and highly flexible mode-order conversion scheme by exploiting reciprocal mode transitions is proposed and investigated in detail, where an inverse/asymmetric input taper and an asy…
