Abstract

In this work, we design a 60-degree waveguide bend with a wide high-transmission bandwidth (~ 9.8% of the center frequency, or 150 nm at the wavelength of 1550 nm) in a triangular photonic crystal slab. Within the high-transmission bandwidth, power reflection at the bend is found to be lower than 2% of the input power. Based on this 60-degree bend, a sharp 120-degree bend with a compact device area is proposed. Similar transmission efficiency is also found for this 120-degree bend.tis@ep
