WebWe compare two silicon-based broadband 3dB directional couplers (DCs) with different structures and assess their fabrication tolerance and temperature tolerance. One broadband DC comprises 3-segment waveguides, with a device footprint 32μm×1.3μm, the other comprises curved waveguides, with a device footprint 20μm×3μm. By adding … WebOne method to make waveguide or fiber couplers is to use straight sections of the guides where the evanescent modes of one guide overlap with the modes of a second guide, eg, a directional coupler. The light from one guide slowly …
