Ultra-broadband Silicon Photonic Multimode Interference Coupler Halir, Robert Cheben, Pavel Luque-González, José Manuel Sarmiento-Merenguel, Jose Darío Schmid, Jens H. Wanguemert-Pérez, Juan Gonzalo Xu, Dan-Xia Wang, Shurui Ortega-Moñux, Alejandro Molina-Fernández, Íñigo Células solares In integrated optics, multimode interference couplers (MMIs) are used as light-wave splitters and combiners in a wide variety of devices ranging from spectrometers to sensors and coherent optical receivers. While their design and operation is generally well understood [1], the operational bandwidth remains limited. Here we present a sub-wavelength structured MMI, shown in Fig. 1(a), that overcomes this limitation and experimentally demonstrate a bandwidth exceeding 300nm at telecom wavelength, with more than 500nm bandwidth potentially attainable (as per 3D-FDTD simulations). 2017-04-20T08:50:16Z 2017-04-20T08:50:16Z 2017-04-20T08:50:16Z 2017 conference output R.
