SOI zero-gap directional couplers are studied by using large cross-section single-mode rib waveguide theory and dual-mode interference principle in silicon dire
A numeric reasoning method has been established.With this method,computations oflogical values are only needed instead of step-by-step matching reasoning.Reason
In the present paper,a silicon nitride-based composite processed with rare-earth oxidesadditives is presented.Its bend strength can be maintained at a value as
