Silicon photonics enabling ultra-small photonic integrated circuits induces a necessity to develop efficient optical couplers that connect silicon waveguides with optical fibers or offchip other optical components. Vertical couplers are promising for both wafer-level testing and the integration of optical components on the chip surface, but so far grating couplers have been the only solution virtually. Very recently, we have developed a few-micron-scale vertically-curved silicon waveguide… CONTINUE READING
