Abstract

We propose an ultra-broadband, compact size and low loss 3-dB adiabatic subwavelength grating-based power splitter based on the silicon-on-insulator platform. Simulation results show that our proposed device has an operating bandwidth of 250 nm, covering the wavelength range from 1400 to 1650 nm, while the device size is reduced to 11 μm and the excess loss is as low as 0.22 dB. Compatible with mature CMOS process, our proposed subwavelength grating-based power splitter shows excellent potential for large-scale photonic integrated circuits.
