In this Letter, a four-channel silicon photonic mode-division-multiplexing (MDM) and wavelength-division multiplexing (WDM) transmitter chiplet is proposed over a 1.65 mm 2 footprint, utilizing add-drop micro-ring modulators to simultaneously achieve electro-optic modulation and two-wavelength multiplexing.A dual-mode grating coupler with a side-distributed Bragg reflector for equalized two-mode coupling is realized with high chip-to-fiber coupling efficiency, so as to support the MDM optical fi...
