Design and optimization of an inverse-designed mid-infrared 1×6 coarse wavelength-division multiplexer<p dir="ltr">In photonic integrated circuits for on-chip optical communications, compact wavelength-division multiplexers/demultiplexers with high integration density are indispensable functional components. Inverse design methods have been demonstrated significant advantages in reducing photonic device footprints and enabling highly compact device architectures. However, when applied to wavelengt
