摘要：
Based on a photonic-crystal slab structure, a 60 degrees photonic-crystal waveguide bend is successfully fabricated. Its bending efficiency within the photonic bandgap is measured, and near 100% efficiency is observed at certain frequencies near the valence band edge. The bending radius is similar to1 mum at a wavelength of lambda similar to 1.55 mum. The measured eta spectrum also agrees well with a finite-difference time-domain simulation.
