Coupling between PhC membrane and lensed fiber: Simulations and measurements

“…In parallel to tapering the waveguide, the mode field radius of the single mode fiber should be adjusted to fit that of the waveguide. In order to improve the coupling efficiency, either macroscopic objectives [3] or micro-lensed fibers [4], [5] can then be used. Micro-lensed fibers are more interesting because of their compactness and better suited for commercial applications, where installation and packaging play important role for the success of a component.…”
