title: Compact and low-loss silicon power splitter based on inverse tapers.
abstract: A compact, low-loss, optical power splitter based on inverse tapers is proposed and fabricated on a silicon-on-insulator platform. High efficiency mode evolution between the fundamental mode of the input waveguide and the super mode of the output waveguides is realized using optimized tapers. A 1×4 splitter with insertion loss lower than 0.4 dB and uniformity better than 0.68 dB in a wavelength range from 1510 to 1550 nm are demonstrated within a footprint of only ~75 μm(2). These properties are very promising for ultrahigh density photonic integration applications.
