<p>A silicon mode multiplexer (MUX) based on the three-stage cascaded wavelength insensitive coupler (3CWINC) is proposed and numerically demonstrated. The 3CWINC is composed of three identical asymmetric directional couplers (ADCs) and two different phase adjustment regions placed between each ADC. We numerically show that high-performance mode MUX is easily designed using 3CWINC, which consists of ADC with transmission higher than 25% over the entire operating wavelength range. The designed TE0-TE1 mode MUX based on 3CWINC can maintain transmission 94.4% (-0.25dB) or higher even if fabrication error of waveguide width occurs up to 10nm.</p>
