Broadband and Ultra-Compact Adiabatic Coupler Based on Linearly Tapered Silicon Waveguides
Abstract
2x2 couplers are crucial in many photonics applications but are often wavelength-sensitive. Alternative designs could be large, complex, or lossy. We present a broadband ultra-compact adiabatic coupler with minimal coupling variation and the least silicon taper length of 1.44 um, to our best knowledge.
