Phys. Rev. B 62, 4488–4492 (2000)Waveguides and waveguide bends in two-dimensional photonic crystal slabsReceived 24 February 2000; published in the issue dated 15 August 2000 We present theoretical studies on waveguides and waveguide bends in two-dimensional photonic crystal slabs. The waveguides are created by either filling up or decreasing the sizes of air holes. Our designs focus on using the frequency range where the waveguide mode is nonleaky. It is shown that high transmission through the sharp bend can be obtained for some frequency ranges in the triangular lattice slabs. The waveguides in square lattice slabs are also investigated. © 2000 The American Physical Society URL:
